Problems going into gear!

[Danny Stephens]

I am having problems getting my TJ to go into gear but not all the time. I have replaced slave cylinder and throw out bearing. Only thing left is replacing the clutch. Sometimes I can get in it and it goes right into gear smooth as can be and sometimes it just want go into gear at all unless the Jeep is not running. It’s not slipping or anything like that please help! Any advice or any info would be greatly appreciated.Thanks Danny 97 TJ 2.5

Drain it and put in Redline mt-90 fluid .

Some fluids mess with synchronizer movement due to viscosity.

Sounds like the synchros.
Have you tired double clutching?

 

[Danny Stephens]

I will try that Andy and I have tried double clutching. I will change fluid in transmission and see if that helps.

That's an age-old problem that has been discussed extensively without a single cause or reliable cure ever found. My AX-15 had that problem and as good as Redline MT-90 gear lube is, it did not fix the problem. Neither did replacing the clutch, pilot bearing, or throwout bearing. Not that I replaced those items to fix that particular problem but it didn't help.

So do you think I may need to check in to a new trans or what would you recommend Jerry?

I can't say. I just lived with mine but yours may be worse so I don't know.

Ok thanks Jerry

From a stop shift to second then to first Works for me

I can see that working to stop the rotation from engine vibration.
