So I recently got my hands on a second jeep,and I love.im having an issue with it tho.when the jeep is cold I can shift in to all gears just fine while the motor is running,but once I've ran the jeep for a little while like let's say a half hour,then it becomes hard to put in to 1st gear.ive gotten used to putting it into gear before I come to a stop and just keeping my foot on the clutch so I don't hassle but that's starting to get old.so what I've done is gotten home and had my son help me bleed the clutch and that seems to help out until it warms up and I have to keep my foot on clutch while at a light.i don't want to just start swapping parts until I get it right but I want to fix it.my jeep has an inline 6 with a 5 speed manual Trans,it's a 1990.any help would be much appreciated,thanks

Mine does the very same thing with the 2.5L and 5 speed. Looking forward to hearing what answers are.

change your fluid in trans.. But this sounds like something internal that will require repair of bearings or pilot bushing.
I use 10w30 motor oil..
some use redline MT ...
see which gives you better results start with the cheapest one.. CHEAP DINO OIL....

 

[Ceezz]

I'll try that today hopefully that helps out

Also I forgot to mention that when the issue of being hard to put in gear happens it seems like the pedal softens a lil bit.also I don't see any fluid loss

Agree.. Start by checking tranny fluid! I recommend Redline.

Well a MC or slave can have a internal leak or blow by.. The seals that hold pressure start bleeding off pressure..

Some of that is normal high mileage wear on the syncro.

First, change the fluid. I also use Redline.

When you go to put in first, push it gently till it resists then let off the forward pressure then push forward again. It should then go normally.

Buying oil right now will update as soon as I can

I had used Redline GL4 for about a year, I grew so tired of it being hard to shift while cold so I tried Amsoil GL4... the difference is so much better.

Also cheaper than Redline with a membership

Redline 4qts $76.08
Amsoil 4qts $45.80

So I went and bought 3 quarts of Lucas synthetic and a quart of penzoil synchromesh,fill it until it leak out a little bit form the fill hole,ran it around for a lil bit,so far were good.i will know for sure when I'm on my way home from work.the LA traffic will for sure put it thru the test,will keep you guys updated

 

[Ceezz]

Well that didn't work,lol.going look in to putting a new clutch in to it.sometimes when I release the clutch it feels as if I'm letting it kinda quick

 

[JeepSolid.Dale]

Sounds like the fluid change helped? But there's still issues..

Everything says you have a bad clutch problem, not a trans, but I think it is the Master that's bad, when you get in traffic and everything under the hood gets hot, it's there and not when cool, so the master could be getting hot and bypassing. JMO

 

[Ceezz]

Yea I think your right.i really like my jeep so I think I'm going to just replace the clutch and the master cylinder

So did this solve your issue? I'm having the same problem

my 90 will do that when water is in the transmission oil .
