Hey I was wondering if anyone on here could help me address a question about my transmission. I had it rebuilt a year ago, and it always for some reason popped out of 5th gear when you let off of it (mostly when coasting down a hill) ever since it was rebuilt. through out the year it has gotten worse, and today i'm pretty sure the nut came off. I was driving 55mph with my chip off and then it just left, it had a very quite grind that you could bearly hear. All other gears work fine, is there anything ya'll suggest as far getting a new nut? welding it back on? or just light the truck on fire?
