Trans grinding

[eddie12388]

I have a 196 CJ7 with a T-5 tranny there's a rattling noise when I let off the throttle coming from the Transmission any ideas? i can shift fine without any noises It only seems to happen if I accelerate or decelerate.

I have a T-5 also. I just finished refurbishing a NP435 to replace it though and will be installing it soon.
I’m not really sure what’s going on with your T-5 . But, if you were closer, I’d just give you mine.

I’ve rebuilt a few transmissions and transfer cases. Not an expert, but really all you can do is pull it from the Jeep & take it apart and assess.
Look for smoked synchronizers. They’re the smaller rings of gears that ride on each side of the sliding selector gears. They have little engagement teeth which can become rounded/ground off.
Look at the larger main gears for excessive wear, super-shiny teeth tips or chipped teeth.
Pry carefully against the main shaft & counter shaft and look for excessive side to side & front to back movement, which means worn bearings.
Most rebuild kits come with new synchros, bearings and fork shoes (the wear parts). If you need any new gears or shafts, that can create alot of searching.
There are a lot of great people on this forum who will help, so don’t hesitate to ask questions.

Yes, I know from looking at your signature. If you click on the member's picture/icon you'll see where that member is from.
Unfortunately, I think shipping a 80lb Transmission 1,900 miles is probably more than a rebuild kit would cost, just guessing.

Maybe, just maybe, it’s a rear driveshaft issue and not the Transmission . You might luck out and only have that as an issue.
Do you know how to check for that? That would be the rear u-joints and the slip joint.

Do you know what gear oil/fluid is in the Transmission ? When I had a T-5 , it would grind on shifts 3-4 a fair amount of the time. Drained it and went with Synchromesh, was quiet as a church mouse until I pulled it for a T19. Might be worth a try.
