Shudder in reverse

[Chevy1925]

What can I check on the t case? Truck has 260 on it with original transfer to my knowledge

I should probably mention its an Lmm with a gmax kit I installed about 20k ago

i honestly couldnt give you the best place to start looking without being there but generally the worn snap ring groove in the rear case half, shift forks, or a damaged tone ring can cause weird stuff to happen like your talking about. dont take what im telling you to heart though. this isnt something easy to point at over the net

Thanks, I appreciate any help I can get.

I'll check it out when I get it back on the lift. I checked the output and it didn't seem like it was loose but I could have missed something.

Yea I know what you mean on online diagnosis lol. I'm just kinda at a loss of ideas since I've never been down this road on one. From the reading I've done it sounds like a apply piston seal problem, I just want to be sure before I pull the trans and tear it apart.

Has anyone been able to figure this out?
I got into a race yesterday and pushed her a little hard and now I get that weird vibration in reverse.

The last post is from 2015, I'd recommend starting your own thread in "Mike L's Trans Talk".

my issue would not cause a weird vibration in reverse. you have something else going on.
