I searched through a ton of posts here and couldn't find anyone with the same problems I am having. i have rebuilt a few 700's but never seen one with this problem. I would appreciate a little help, thanks!

I have been babying this transmission while saving for an upgrade, so it has little to no abuse since I bought it.

I drove home from work at about 8 pm and had no issues. The next morning when I left for work I had bad slipping in 1st and 2nd, but 3-4 have no ill effects that I felt.

I checked the fluid and it is sitting a hair under the top of the checkers when hot, but is full of bubbles. Fluid is a decent red, has no noticeable particles in it, and doesn't smell burnt. It has been about 10,000 since my last filter/fluid change.

What would cause slipping and bubbles besides being over/under filled? My only thought was if my filter neck cracked and was sucking air instead of fluid, resulting in a loss of pressure. (or my 1-2 clutch pack is flopping around in the pan causing agitation )

Any Ideas? Thanks!

 

The forward apply piston may have cracked. Just had one here do the same thing, and that is what it was.

 

Thanks for the tip. Im going to tear it apart this week and see. Ill let you know what I find.
