housing that fits in my 700R4 tranny. I put in
a new O ring, but it still leaks. I can't seem
to get the housing in there tight enough.
Anyone else have this problem and come up with
a solution. Maybe I can double up the O rings
and that might work. The trouble is the bolt
and bracket that hold the housing in place are
not made to put much force on the unit.

Mine appears to be leaking around where the gear passes thru the housing. All new GM stuff, I even put another seal on gear, still leaks some. Just enough to leave spots on the floor.

the answer before me please post it or contact

All new GM stuff, & it leaks. Brian | | | | | Joined: Oct 2003 Posts: 36 Junior Member | | Junior Member Joined: Oct 2003 Posts: 36 | I have the same problem on a turbo 350. I had it rebuilt by AAMCO. Since they rebuilt the tranny by itself, I have to get it inspected by AAMCO once I can get my truck on the road. I will mention it to them and get back to the board when I find out their solution.
