I know, from what I've been able to google and search for... I've been unable to find a definitive answer. I'm hoping for some assistance.
This is my first post here as I've really had no issues with my TJ at all. It's had a transmission issue since I bought it and I knew at some point, it was going to have to be rebuilt. It's got 180,000 miles on it after all.
I've had to do some minor things here and there, but recently, the pilot bearing failed and scored the input shaft pretty heavily. Since I'd been limping it along for quite a while with bad synchros, it was time for a rebuild.
I found a shop in San Antonio that rebuilds them for a really reasonable price, far less than anywhere around Houston I could find.
Installed and ready to start rolling again with 75/90 lube in the case and holy crap is it loud. Really loud. It sounds like I've got a supercharger under the hood. Only in 1 2 and 3 though. 4 and 5 are normal and quiet just like I've become used to. I can live with the sound if necessary, but man, it just doesn't sound right.
So...all that said...Is the 75/90 the right lubricant to use in this transmission? I've seen lots of information out there. I called the manufacturer. He said 75/90. The computer information for the mechanic called for 75/90.
Something's not right so I'm reaching out.
