T5 transmission help needed
I have a used t5 that I swapped in, due to the old t5 going bad. I filled it with 80/90 GL and have done a few short trips around town to make sure everything was good and to look for leaks. All has been good and I figured it would be OK to take to work ( 20 mile drive ). I just wanted to look for any leaks, to see if all was still well. It is completely soaked with gear oil and looks as if it was coming form the breather. Am I using the wrong oil ? It did have what looked to be gear oil to me, in there before. I'm confused....
Someone please help.

Running the same stuff in mine. O'reillys 80-90. I do have some leaks, too, though.

I'm not talking leaks here, I'm saying it saturated and has a puddle under it. Something is seriously wrong.

Check to see if the oil is coming from a weep hole between the trans flange and transfer case. If that is where it is coming from, then you have a rear seal on the transmission that is leaking.

No it's not coming from there, plus I just put a new seal int there. I'm thinking the 80/90 GL is too thick. It is deffinately coming from the casr breather and spilling every where. BTW you t5 looks awesome, wish mine did....

How much did you put in?
Don't mean to insult you but it sure sounds like it is over filled if it's coming out the vent. Thicker gear oil typically wont cause what your explaining..

A little over two quarts is what went in. I pumped it in until it started to come back out. I was doing a online search ( now ) and just read that I should be using 70W GL instead of 80/90 W GL and that world class t5s used auto tranny fluid. How do you tell world class and non world class apart from each other ? Anyone know?
Thanks.

The Borg Warner T5 in your Jeep isn't going to be a World Class model that's for sure. AMC never used them, they mostly sat in Ford Mustangs I believe.

A friend of mine said that the case breather might be plugged. Any thoughts on that ?

I thought that is what you were saying was leaking.
Edit: I see in the above pic that it is different

Not going to touch the correct fluid subject but Keith, is that a polished T5 or just real shiny paint?

That's what I was trying to tell him.... Is there any reason it would build up pressure to leak from there? I also just read a long post on which oil to use, it seams that everyone is using something different. For now I will just try to top it off with more gear oil to get it home. Then I will try to come up with a plan, not sure what though......
Thanks.

Not a T5 but a T4 and it is powder coated with Eastwoods "Reflective Chrome" powder. I just love at home powder coating, it's so easy it's pathetic.

I'm betting that it has something to do with the gear lube that you put in. I remember the lube for the T5 was a "special" product from AMC/Chrysler that looked similar to ATF, but cost about 4x as much. I spent a lot of money on that stuff with the three T5 transmissions. I put in. My transmissions weren't World Class ones either.

I use Royal Purple Syncromesh fluid as it is designed for manual transmissions with brass/bronze type blocking rings as the T4 and T5 have.
