T176 Tranny after rebuild making problems.

Hello, Ive just signed up to the forum, although ive been reading in it for some time without registering.

Today I finished rebuilding a T176 for my CJ, as a replacement to the SR4 I had before. I did the rebuild myself for the first time, and after finishing and installing I found the transmission to be working pretty good and smooth, but with two noises I cant explain.
The first one is a whining sound on gears 1-3, and the second noise is upong deceleration on 3rd gear only, a quick ticking noise.
what could these noises be?

In my rebuild I replaced 2 bearings, 4 syncro's, all roller bearings and the countershaft, and a new TOB.

Thanks in advance, Shlomi.

Main or counter shaft end play/preload is off.
Are you sure you put ALL the thrush-washers back in in the correct order.
Ask me how I know this

on the gears 1-3 noise it probably has something to do with the countershaft as 4th gear doesn't use it under load. As stated above, double check you have all the needle bearings in, the thrust washers are in place properly and the end play is in spec.
The second noise could be related to the first if there's movement of the countershaft. Mine would periodically pop out of 3rd when decelerating and i had a 1-3 gear whine like you.

Hmm, how do you know this?

Damn, this is a lesson I wont forget. The place I got the parts from didnt have the thrust washers for the countershaft so I returned the old ones,
yeah laugh at me. Nah, alright, if you are sure of this, Ill get her off the jeep and replace em.
Im wondering if ill have to pull out everything, or if Ill be able to somehow not pull our the bearings.

Well like what? The bearings are new, so slop in the mainshaft sounds less possible to me.

Like I said in my first post. Preload and end play on the main and counter shaft. Along with the thrush bearing installed in the correct order of assembly
Did you use a dial indicator to check endplay to set your preload?
What tranny manual did you go by?

Sorry I've got a little problem with the language, what do you mean

you gotta check this stuff also.

But I just used a thickness gauge.



Although I didn't set any preload, I thought that was only on tapered bearings or angular contact ball bearings.
