millican Posted July 1, 2014 Report Share Posted July 1, 2014 After carrying around a transmission in the back of my truck because I'm not supposed to have car parts lying around the house, I opened it up today and seperated the aluminum case from the other stuff. It wasn't as bad as I was expecting, but the problem is still pretty obvious. The one odd thing is that part of the toothless gear is still there. Shouldn't these have been lined up perfectly? So, the case is apart and will be recycled soon. I'd rather it go to use if someone needs one to do some 4-speed to 5-speed voodoo stuff I've heard aobut. Quote Link to comment
datzenmike Posted July 1, 2014 Report Share Posted July 1, 2014 The counter drive gear is just narrower than the main drive gear is all. Your front case is for a Z series engine. You could use it to convert another L, LD or CA series FS5W71B to work on an Z series engine. That's about all. The front case of a five speed does not make a four speed into one.

millican Posted July 1, 2014 Author Report Share Posted July 1, 2014 Ahh thanks. I'm not familiar with the Z-series engine, so I'll take your word for it. It will definitely be nice to not have this in the back of the truck anymore. Quote Link to comment
ggzilla Posted July 2, 2014 Report Share Posted July 2, 2014 It looks like the input gear on the mainshaft is completely stripped. The countershaft looks fine. Quote Link to comment
Draker Posted July 2, 2014 Report Share Posted July 2, 2014 Detent failure allowed you to shift into two gears at once? Quote Link to comment
millican Posted July 2, 2014 Author Report Share Posted July 2, 2014 I'm not sure about whether the detent failed. It was going along on the interstate just fine. After a loud clunk, it wasn't going just fine anymore. ;-) The transmission doesn't really look as complicated as I'd expected. It even looks like it could be rebuilt. Quote Link to comment
datzenmike Posted July 3, 2014 Report Share Posted July 3, 2014 Detent failure allowed you to shift into two gears at once? Can't be in two gears at once trans would be locked up and you couldn't take off. Impossible when moving without severe grinding that you'd hear. Perhaps counter gear worn out and the gear lash is totally wrong and wore it out? Quote Link to comment
Master-O-Turbonics Posted July 6, 2014 Report Share Posted July 6, 2014 You can replace the input shaft and counter gear with one out of another transmission, and of course you want to replace all bearings after an event like this has happened to the trans. Quote Link to comment
datzenmike Posted July 6, 2014 Report Share Posted July 6, 2014 The input shaft gear is matched to the counter gear so you will need an exact matching of number of gear teeth. I'd chuck it out and replace the whole thing. Quote Link to comment
Master-O-Turbonics Posted July 6, 2014 Report Share Posted July 6, 2014 I'd pull 5th gear off the countershaft and main output shaft and save them. 5th gear tends to break as well as input/countershaft gears Quote Link to comment
millican Posted July 7, 2014 Author Report Share Posted July 7, 2014 Alright, thanks. I'll hang on to the 5th gear and main output shaft and save them. Quote Link to comment
