YJ Transmission Problem

Re: YJ Transmission Problem
If it is grinding and clunking at speed you have lost more than the
synchro. I have never heard of this happening, but from your
description it is something I would check: maybe the 5th gear has eaten
itself. Spit some teeth, cracked, gone kaput as it were. If a synchro
goes the shifting gets very stiff and it will grind a little. If you
"freewheel" there is no load going through the transmission. And the
noises you are hearing could be a bad gear with missing teeth grindind
against other gears.
It depends on your mechanical skills as to wether you can verify this
yourself. I would drop the trans and split it from the Xfer case and
try manually rotating the input in each gear and see what it feels
like. There should be a little bit of mechanical vibration, fromt eh
gear teeth aligning, but especially once in gear there should be little
vibration. If it is hard to turn then there is a problem. DO not
disassemble your trans. If you suspect a problem, take it to a shop and
have it fixed. Or swap in a better trans. A borg warner T-5 or a New
Venture 3550 would be a good replacements. You can get information on
them from http://www.advanceadapters.com/

Re: YJ Transmission Problem
Synchros have a function while shifting _up_? I thought that synchro
rings were to bring the engine-side of the next lowest gear up to drive
shaft speed while shifting _down_, that's what double-clutching does.
Double-clutching going up is going to spin the gear faster than the drive
shaft.
I'm not a transmission guy, but I'm guessing that a gear that makes noise
when the wheels are pushing the engine has a problem someplace other than
the synchros.

Re: YJ Transmission Problem
Synchros have a function while shifting _up_? I thought that synchro
rings were to bring the engine-side of the next lowest gear up to drive
shaft speed while shifting _down_, that's what double-clutching does.
Double-clutching going up is going to spin the gear faster than the drive
shaft.
I'm not a transmission guy, but I'm guessing that a gear that makes noise
when the wheels are pushing the engine has a problem someplace other than
the synchros.

Re: YJ Transmission Problem
It's the cluster, not the driveshaft, the driveshaft is as
disconnected and the input shaft, between shifts. You may hear a tractor
hit the jake brake between shifts to slow the counter shafts down for
next gear up leaving a stop. Or you may hear the engine race up to spin
the cluster faster for the next gear down, for engine braking.

Re: YJ Transmission Problem
yep, you got synchros on both sides of each gear.
one for upshifting, one for downshifting.
