Default Wierd reverse problem after shift kit install, and wierd noise....

I install a shift kit from FLT today and now my reverse is acting kinda strange. When you first put it into reverse it and give it a little gas, it kinda studders, kinda like it is popping in and out of gear..... But then again it kinda acts like the rear brakes are locking and unlocking.... BTW I had gears installed today... I adjusted my tune via EFI live for the new gears, so that is not a problem..

I am kinda thinking that something in the rear brakes is messed up.... Another thing is that if you put it in gear and let your foot off the brake and coast the rear makes a wierd sound, kinda like an old warn out belt....

Any Ideas...

I fixed the wierd reverse noise, I forgot to tighten 3 8mm bolts on the back of the tranny that bolt directly to the space plate, kinda below the valve body. I guess I over looked them when I put on the valve body.

Performabuilt pointed me in the right direction!!!

Good to hear you found it, that was my first thought for the problem. I think I tightened those bolts about ten times in fear of forgetting them.
