944 NA Transaxle Help

[bklinetob]

I need some help with my transaxle.

Last week I re-assembled the gear carrier. I pulled it apart only for inspection and re-seal purposes. Put everything back together; no problems, everything shifted fine. During installation into the car, I found that the coupler between the input shaft and drive shaft is too short-- my only conclusion is that the input shaft is shifted to the rear of the car, within the transmission.

I'm somewhat puzzled since, besides pulling 5th gear, I shouldn't have changed anything that affected the shaft thrust. During re-assembly, everyting seemed to bottom into place, with all the original spacers put back in the same order (per factory manuals).

I've since pulled it apart again, and am re-assembling, looking for clues as to what affects the thrust. So far, the rear-most ball bearing seems to be the key.

My questions: Does anyone have access to a transaxle and can provide me with a dimension from the transaxle-to-tunnel flange to the end of the input shaft? With this I can know where the shaft should be, without having to reinstall it in the car. Manuals don't seem to have this info.

Additionally, any technical advice would be much appreciated.

Thanks!!!

Brian,

It took me 3 hours and numerous searches to discover the fix to this problem after i replaced my transmission.

I am now an expert at removing and installing my transmission though :0). I did it 4 times in total.... ouch....

Solution: You're going to kick yourself...

Fit transmission as you would normally.

Attach coupler to drive shaft and secure with bolt.

Use large screw driver or pry bar through small aperture to lever coupler and drive shaft back towards transmission until you can fit the second bolt in the coupler.... I had to move mine only by 1/8th of an inch.


Hope this is what you're looking for.

Nige.

I'm tired of kicking myself; the wife has taken over.

Thanks for your help. I've been racking my brain with this thing trying to figure out how the shaft could have been off.

As soon as the new gasket set arrives, I'll reinstall it.

Nige is right. The tranny input shaft does not move. It is the torque tube drive shaft that can move either towards the front or rear of the car. Once the tranny is up and the shafts are lined up, install the coupler on the drive shaft first and move it back with a flat screw driver through the hole in the torque tube bell housing. Good luck.
