Transmission almost installed ! ! ! ? ? ?

Ok

I've got the new-used transmission within 1/2" of fitting and it won't go any further. I've pulled it off and examined the shaft, which looks ok?. I know you're not supposed to force it, just a push, twist and a jiggle to line up all the splines and grooves. Then it's supposed to slide right in. I get stuck with the top flush and the bottom out by 1/2". I've tried clamps, channel locks occasionally I can get one bottom bolt in, but not the other. Any ideas other than drink a beer and take the rest of of the day off (already there).

Tomorrow, I'll start over. One problem: working on my back, in the dirt on a hill.

Couldn't change the trans filter, stripped two torx. Couldn't change the Torque converter, my airgun nicely rounded the last bolt! This is a $650. car.

The trans isn't lined up right, if it's touching the block at the top but is 1/2" away at the bottom. That tells me the tail of the trans is too high relative to the input shaft...

Whatever you do, DON'T try to "pull it in" with the bolts. That is a sure way to crack the bellhousing or block, displace the torque converter support bearing inside the trans, or bend/break something else.

Is the converter properly seated in the trans? Did you clean the crank recess (where the converter pilots into the crank)?

Edit: I just read your post again... are you saying the converter is still attached to the flex plate? If so, how do you know the converter is going into the trans far enough and the oil pump drive slots are engaging the pump?

Thanks Doc

It's nice to get confirmation. I figured the splines hadn't engaged correctly. I just have to support the trans to match the angle of the engine, against the angle of the hill. I'll level my ground board to match the car, third time's the charm

The last time I did this in a parking lot. I put the smaller manual transmission on my chest and bench pressed it in to position, went right in.

Now, I'm too old and smart to attempt that again.

You have to get the torque converter off the fly wheel first and put it on the transmission or you could screw up the whole job ! You might want to cut the bolts off the torque converter then get new one's

Oh boy, that's the good part about weight traning...

Ok that sounds like it makes sense. Three bolts to line up as opposed to splines and grooves. Time to start drilling. The new(ish) Torque converter, like the trans only has 94k miles on it.

I drilled out the final torque converter bolt, put the new converter on the new tranny and spent a couple of hours trying to balance the whole mess on my floor jack. It all wants to go downhill. The front is on a milk crate, the rear is on a bunch of 2x4's. I'm 15 minutes away from bolting up and I'm down to 1 TC bolt, so it's time to stop.

Much easier with the torque converter installed on the tranny.
