I dont know if there should be any. Normally play in the output shaft is signs of a bad tailshaft bushing isn't it? I would imagine that play in the output shaft combined with that swinging driveshaft would cause some serious vibrations.
But I dont really know much about it so I guess wait for a more educated answer .
If you are talking about end play it is measured from the input shaft only.
If the transmission is positioned so the input shaft is pointed up the output shaft has to be towards the back of the case.
The input shaft is now pulled upwards and the result is end play.
Ok I understand what you're saying about measuring input play. I thought I heard that the output shaft play could be separately measured from the back of the transmission. I'm half way thru assembling the transmission...I haven't installed the input shaft yet and just happened to notice some play (back and forth) in the out put shaft. Perhaps this is normal and maybe why it was not mentioned in the book.
IF there is too much end play of the input shaft after the pump is installed ....... there are shims that can be installed under the bearing on the out put shaft to tighten up the end play of the tranny at the input shaft.
I have never checked the end play of the output shaft by it's self as stu is pointing out here
Thanks all, I did measure the selective thrust washer and endplay when I disassembled the transmission so hopefully when I put it all together the final endplay will be close to ideal. I think I mixed up the endplay measurement procedures for the TH400 with the TH350...anyway the issue is much clearer now.
