94 530i shift problems

So I have a 94 530i, auto trans. and it will drive but only in what feels like first gear (25mph top speed) I can move the shifter into the manual gears and I can feel and hear the trans try to shift but it just won't up shift. I can go in reverse perfectly fine with out any hiccups, but when I try to drive it, at first it seems fine at 25mph and lower on flat roads but instead of up shifting at a certain rpm, it just revs as if it's in neutral but still maintains just enough of that power to the wheels to keep it driving steady but at slow speeds, and it definitely won't go up hills of any kind while in drive, but again will climb them without issue while in reverse. This started happening after the car had a throttle body swap and the throttle line was adjusted wrong at first causing me to be stuck in second gear while at a stop light which I know probably didn't help anything, but I adjusted it to the correct position asap and then every thing was fine until a few hours later I tried to go some where and as soon as I went to some what heavily accelerate, the car jumped out of no where then started acting just how it is now. Can someone please tell me what could possibly be wrong with my car? I've checked the trans fluid and it was fine, and I didn't get a cel but I had some one tell me to do a stomp test anyways and I got 1444 (no fault) so I reset it, let it run and switched it through all the gears and did another test and still no faults

I'm not too knowledgeable when it comes to trannys, so if this sounds like a problem with the trans it self, then please be specific on what exactly you think is wrong with the trans

If only the throttle body was changed I can only assume the tps isn't plugged in or incorrectly adjusted. Especially if you have a electronic transmission(economy sports etc)

+1 on above (hi paul). If that does not work it could be the valve body stuck. Not to hard just fiddley to clean.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?

The throttle body was changed, to one that is almost twice the size of the oem one. And the tps is plugged in, but I'll have to run some test on it with my meter. When looking up guides for the t-body swap that I did, I never read anything about changing the tps as well. Could this be my issue?

If you put the original tps on your new throttle body then the best thing you can do put the old one back on & see if the problem disappears.
Just wondering if your using the original AFM/MAF box?
Hey BMWFF
Also don't forget if the tb is twice as big than a 2.5 degree movement is like 5 degree turn on the old tb its probably confusing your DME/ECU.

The TPS needs to be checked for smooth (electrical) action and be correctly adjusted radially with the throttle itself.

Yeah, I'm gonna check it later on today with a multimeter and see what comes up, and btw. If I do end up needing a matching tps for the new throttle body where can I get one online? The new throttle body is off a e38 740il I believe

I was just looking at other areas, because my tps is 26 years old & just about to hit 200000kms (125k miles) & no problems YET! But yes a faulty tps will make it difficult to change gear, I gather yours is the round plug type with 6 wires (3 are for the ecu, 3 are for the transmission program). There are two types round 6 pin(electronic transmission) & rectangular 3 pin(kickdown cable transmission). I have 1 on 1 car & 1 on another car. Get the multimeter on it & see what you get.
I'll just add get the part number off the tps, I remember trying to find a spare for mine cause I thought it was giving me issues didn't bother with BMW (they want $580 for a bosch idle control valve yet the aftermarket place will sell the same bosch icv for $300 less) tried bosch & it was a 3 month wait from Germany. So go second hand any 3,5,7 series from 1988 - 1995 with a electronic transmission will have it.

Alright thank you so much, hopefully this will do the trick. But it is the 3 prong tps and I do have the kick down button. But my car is 20 years old with 198000 miles on it... Lol

Hopefully it does, my two are 88's one electronic one cable. But I guess you learn something new everyday I figured the electronic became standard after at least 1990. In that case the tps should be much cheaper. When I was talking about the tps before I was talking about the electronic version but I've never changed the 26 year old 3 pin one either, YET. If you check a few pages of threads back a couple of members have had transmission problems with the kickdown cable transmission as did I but your problems started after a tb chsnge, fkn weird.

Hey I'm starting to get confused which gear lever picture looks like yours the black or tan?

The black one except it's a u.s. version so it's all backwards, but it still has the traction control switch or whatever you want to call it

Also, when the pan was dropped the fluid was black but didn't smell very burnt at all, and there was no metal chunks or shavings in the fluid or pan/magnets that were big or bad enough to be of any concern

Yeah check the tps & also did you have to adjust the accelerator cable?
This is why I got confused the tan pic transmission is not electronic nor is my other e34 that I stripped for parts & they have the retangular 3 pin tps. But the black pic is elecronic & has a round 6 pin tps. Guess BMW split the wires at the ECU box now. Did you change the filter when you did the oil?

I never had to adjust the actual accelerator cable, but what first caused me problems was (I'm just assuming this because idk if I'm correct on what it is or not) but there's a second cable attached to the throttle body lever that I believe is a cruise control cable and the plastic bushing thing that is supposed to hold it in place is broken and whenever I pressed the pedal 3/4 down it got stuck and caused the accelerator to get stuck but I got that all fixed up and the car ran perfect and was shifting normal and everything for the rest of the like 25 mile drive home, and the tps is a black rectangular 3 pin plug and I was getting some weird readings while I was testing it with my meter and so just in case I do have to replace it, I went ahead and traced the wires back to get an idea of what it'll take to do the job and they looked like they went strait from the tps to the big round plug (like 20+ pin) that goes to the ecu box. But I will have to wait till Tuesday for me to get a trust worthy reading on the tps cause I was having to use my cheap meter cause my really good one that is never wrong is at school and I'm still on winter break (I'm in school to be an electrical engineer but this old school wiring still throws me for loops xD). But no I didn't change it because I was told by a friend that the 530i came with a life time filter that I should never have to replace but today I did a little research and I now believe that I was informed wrong and that the lifetime filter was used on the e34 530s but not the year mine is, so I pulled the filter and am planning on replacing it after my next pay. If I get the time for it tomorrow, I'll take and post pics of the shift lever, throttle body and it's cables, the tps plug, and if you would like to see it, the path the wiring takes to reach the ecu

And if I get the time this weekend, I plan on pulling the valve body and checking it out and cleaning it. I've never really known much about transmissions and after doing a lot of research with this problem coming up, I just found out how exact the vb has to be and that literally one human hair can make it work incorrectly and with how bad of maintenance the last owner of the car maintained on the car, I wouldn't be surprised if there's something inside of the vb

Now I really confused, not with what you said. Do you know what engine it is eg m20 m30 m50 etc? Cause I'm looking at the bentley service manual page 130-8 about testing the tps & apparently the retangular tps is for manual transmissions, see pic. It sort of makes sence since my two autos with triangular tps aren't electronic they have this cable to drop down gears when accelerating, see pic, they still however have the button under the accelerator but I read there not plugged in it just regulates the depth the pedal can go. This is getting weirder. Also since you have the transmission pic from earlier do any letters appear on the right hand side of your cluster like E, S, M next to what gear your in?

I'm beginning to think that I either have a one of a kind bmw when it comes to specific parts under the hood, or it was astonishingly put together in a working way with random ass parts from other bmw models. It's definitely not a manual trans, the button under the pedal "kick down" button works FOR SURE (after noticing it for the first time, I put that button to the test on a regular basis, especially during street racing. In fact, it's the secret weapon I have that gas allowed me to win races that I should have otherwise never had a single chance in hell of winning, because what it does is drops the trans down to the most optimal gear so it will accelerate as fast as it possibly can with those current driving conditions) and I have what I believe to be an m60b30.. I sadly haven't ever actually gotten around finding the blocks serial number and look for it online, I've always just gone by what the old owner said which by judging how everything else with the car went while in his possesion makes me a stupid fool for just listening to him and not checking for myself, but he told me it was a 3.0 v8 which I was shocked about it even actually existing because before this car, especially in a car weighing almost 5k lbs. And I have no clue what or where these letters are that you're talking about. If your asking me if their by the shifter, then no. All I have right there is my prnd234 shifter and the traction control switch thing to the left of that. And that's all there is on the center console piece

I actually saw a 530 the other day it parked next to my misses micra as we came out of a shop it had a v8 badge on the left side of the trunk lid by the time I saw the badge he was in the shop. But the pics show the letters I'm on about.

Ohhh those!! That's what I thought you were talking about after I thought about it, but yeah I have those and normally the first letter stays the same for the most part, and of course the second one changes with each gear you shift into. I can't remember exactly how it works but if I'm not mistaken, the first one changes whenever you turn off and on the traction control

But If it helps any, I don't think I've ever once seen the first letter turn to M, or atleast not that I ever noticed. But I have seen both the S and P

Ok its official your car is Frankenstein, wonder if anyone else has the retangular tps with a electronic auto. I'll just point out my e34 with electronic auto is a japanese import. Can't find any info on when they started building those transmissions.
M is for manual it allows you to begin driving the car from any gear, good for pulling a car that is bogged. You probably don't have it because you have traction control.

M is for manual it allows you to begin driving the car from any gear, good for pulling a car that is bogged. You probably don't have it because you have traction control.
V8 Cars have A S M.
A is the default when you start the car, adaptive mode.
S is Sport, when you place the shifter in any gear number, so anything below D.
M is manual. You slide the switch next to the shifter down then select each gear you want.

M is better for towing via the owners book.
There is also a snowflake option in some cars, with the winter package like mine. Helps when driving below freezing if you hit ice, and it is manual mode, but when below 38degrees F manual changes to this.

The modes have nothing to do with ASC(traction control) except the snowflake option.

Most every E34 with an auto has these switches, except early ones.
You do have this.
