ok so my trans started going out. at least i think its the trans the fluid was smoked.. looked more like used oil than trans fluid... it started by just not grabbing gears right away had to rev a lil more to get it to grab... i know i know but no choice had to get it home and im poor. eventually almost home i lost all forward capability except 1st and od ( this is a manual) and to get those to hold i had to put it in manual and do it myself.. last bit of the drive i had to drive it in reverse to get it home all fast and furious style with people behind me looking at me weird while i signaled opposite to correct for the direction i was going.
so yesterday i swapped in a trans from the yard and i either have the worst luck ever or it wasnt just the trans because i have the same exact issues to a t.. no reverse and have to really rev just to get it move a bit... so my question is could this be the rear differential i read some articles about a spider gear... is there a test i can do to tell if its the dif.. jacked up itll move the tires in forward and reverse but with weight on it nothing backwards and minimal to no movement forward... any suggestions or ideas are greatly appreciated

Your description makes no sense. You describe something that can only happen with an automatic, then you say it's a manual (5 speed?) but then say od (overdrive....and the manual 5 speed isn't an overdrive transmission).
One thing I can tell you: it's not the differential.

You're wasting your time on the diff. IF you have a manual 5 speed, the clutch is fried. Probably nothing wrong with the transmission.

Sounds like he's saying auto trans in manual mode?

I dunno... :dunno: Until he replies with an answer 5 speed vs automatic, we can't give a definitive answer.

sorry about the confusion and late response it is a automatic... 4L30e i believe... i meant i had to drive it home in manual mode only way i could get it past certain gears or to hold any it seemed... never the less i sorted it out today got another trans and put it in an. all is well and back driving fine except advance gave me the wrong replacement nuts for the exhaust pipe to exhaust manifold connection and i would of liked to replaced them as they are well worn to say the least... but seeing how easily i removed the dif and inspected it and now that itll come right back off since i just broke every thing free i would like some recommendations on a rear dif up grade

Ok, your transmission is toast. No, you can't DIY repair it. Replace it with a known good one with a warranty or do a 5 speed swap. Since you have an automatic transmission, it already has a low geared differential. Look at the tag on the rear cover. It'll have the ratio stamped on it. Other than a limited slip diff (which would be nice, but not necessary), you're already fixed up with what you need for torque off the line. Your gas mileage won't be so great, though.
