I was wondering if anyone has changed out the output bushing on the 46RE transmission? I am getting a vibration from 68 to 75 mph and my transmission gets overly warm. It doesn't heat up at all if I keep it under 68 mph and I have a nice big Hayden trans cooler. I was wondering if the output bushing can be changed in the truck after pulling the transfer case, (4X4). The trans was rebuilt about 20,000 miles ago and shifts great and has no other problems. I have had this issue for awhile now and already changed out the transfer case as that was what I thought the problem was. Any help or advice is appreciated.

 

4wd transmissions don't have an output shaft bushing.

 

What's normal trans temp and what's overly warm? What's cruising rpm at 70mph? Also are you still using the stock trans coolers in line with your aftermarket or just the Hayden aftermarket cooler? Dimensions on the cooler?
