The wrangler tranny is a Peugeot like the late 80's XJ I think and is worse than anything they put in a CJ. It needs a different pilot bushing, a pilot bearing for one.

The syncros are thin brass gears.
A straight shifter would be a T-176/177. SR-4's were discontinued in 81 or 82 as I remember.

Will the Chilton's manual show how to overhaul the T-4?

A lot of people have said syncro's are the cause of the trans popping out of gear. The syncro's help the shift collar align with the gear so you can shift without grinding.

The detents in the shift rods along with the poppet balls and poppet springs keep the shift forks in the correct position. I would suggest that you pull the top cover and replace all the poppet balls and poppet springs, lube the rails and put a shift lever rebuild spring kit in it.

That should take a few hours and cost less than 20.00.

Adding to what 243 has already said, I've found that another one of the main causes of gears jumping out is end play in the gears or shafts from worn gears. shafts, bearings and/or thrust washers. Gears with synchro teeth or shift collars that have lost their squareness and become worn and rounded off can be part of the problem too.

I found a local guy that rebuilds trannys for a big outfit in San Antonio and does work on the side, he said that he would rebuild the tranny for $175 and I buy the parts. What do you think? Reasonable?

ok update on the tranny problem. Long story short my T4 had a cracked first gear but in the meantime had bought a repair kit for it and had the bigger problems so I went to my spare chasis which i was told was an 87 wrangler and it had a T5 in it which was in great condition so i ended up putting that in the 84 cj7. So obviously it was not a wrangler thank god. I still need to put transfer case in which has already smashed my little finger and I will hopefully be running again. So anyway anyone need a T4 for parts I have one for sale along with the overhaul kit. Only thing wrong is the 1st gear has a crack everything else is good.

its problaly starting to go bad .but check the linkage it can move and cause the clutch to not go all the way out, go on flat ground and put it into first and see if it moves. the linkage looks like this
dont worry about the lettering stole the pic from another thread. that big thing truns and there is a jam nut behind it .im pretty shure the t5 runs the same style clutch linkage

tranny and transfer case back in and it shifts like a dream probably will never use 5th gear but nice to know what it feels like when it shifts correctly.
