will 90 tranny work with 4bolt

[rallyrat427]

like the tile says ... will a 90 tranny work with a 92 4 bolt rear if i change the driveshaft yolk? or are they different ratios?

You do not have to change the driveshaft yolk. If you are putting a 4 bolt rear in a 90 car, you have to replace the rear end, axels and cups. If you are putting a 90 trans in a 92.5+ car, you have to change the shifter, the bracket for the shifter cables on the trans and transfer case.

I just did the same swap on my 90 tsi and it takes a couple hours but it is really not that bad of a job. All you need to get is the rearend and the half shafts like stated above. Also air tools will help a bit and a prybar.

im putting my motor/tranny in a 92 .. im fairly certain its a 6/4 combo shell

I have done the swap a few times. I find it easier to simply drop the entire rear end/subframe assembly as a whole and swap. This may seem harder to some people, but I feel it's easier IMO. There is only 2 bolts, and 6 nuts that hold the subframe to the body, along with disconnecting the ebrake line and brake caliper, and the four 14mm nuts in the hatch for the struts. Using a jack, the entire assembly can be lowered down, and jacked back up in the accepting car with the help of a friend.

Takes me roughly 2 1/2 hours to do the swap.

Then you will have no problem. Just drop it in and go.

should i swap the driveshaft too? because the spline count is different on the 90 tranfercase

 

[ExtremeDSM]

The spline count is different on the trans side, not the driveshaft side.

sweet thanks

You may need the transfer case to match up to the 90 trans. That is the only problem you may run into...............
