5 speed shifting poorly when hot

[truckeejeeper]

Ok - so I've had this problem for a while. Jeep shifts perfectly when cold. When warmed up, its starts to get hard to get into gears. Could I have the wrong gear oil in transmission? Bubbles/air in clutch fluid? It's a PITA and it's time to address. Anyone else have this problem. Thx y'all.

Red line MTL was what I had to use in my tj for smooth shifting.

Generally the problem is in the opposite direction.

I would wonder if you have some very light oil in there, like maybe ATF.

If you don't know what oil is in there I would recommend changing it. Either Redline MTL or MT-90.

Most important of all, DO NOT USE GL-5.

Shoot- my bad my bad sry- forgot to put in there that I have redline MTL in it right now. Apologies...ok so that is the right stuff I guess. Maybe its clutch hydraulics or something. hm
