Howdy all,
New to the forum and already have a question

Aout two months ago I had the transmission fluid changed, had no idea when it was done last or what fluid was used.
The quick lube place that I took it to, told me that it was a GL3 fluid by mopar, after contacting the dealership.
Before when shifting into 2nd when cold, it would be a little sticky and sometimes even pop out of gear. When the transmission warmed up, everything shifted quite a lot better.
After the fluid change, shifting when cold is still a bit sticky, but now when the transmission warms up, I have quite a bit of trouble shifting in the higher gears as well. Other than I figure the obvious that there is a fluid problem, what is the correct fluid that is supposed to be in there? The transmission is stock and I know the fluid is not redline as they showed me the fluid after they drained it.
What is a good fluid to use and would not damage my transmission?
Thanks

 

if it's a YJ then just 80/90 but if its 5speed then you got other problems,fluids wouldn't cuz that sounds more like a bent shifting fork

 

That or Syncros on their way out.

 

The 5 speed uses auto trany oil dextron 3 aint it? Thats what is in mine.

 

the T-case uses dextron 3 not the tranny

 

what year YJ ?
if 91- you have a AX-15 .....
great tranny except quite touchy on 1-2 synchros when cold ....
I have put some 75W90 synthetic oil in mine ....way better !

 

Oh ya DUH. My trany only has a fine mix of swamp goo and sticks HAHAHA

 

its a 1999 sahara and it takes amsoil syncromesh fluid. can be found at any great canadian oil change around canada.
