I decided to replace shift fork pads and blocking rings to the carbon fiber ones in my tremec 3550. All went well, was pretty cut and dry disassembly and assembly. Got transmission back in car and now 3rd and 5th seem to not fully engage. They will pop out of gear if you don't hold pressure...

88 mustang gt. Did an aod to tremec 3550 swap recently. When swap was first completed it ran like a dream. After dropping the trans to reseal the leaking input shaft bearing retainer and reinstalling, the problems began. So I pulled the trans and replaced everything. Had the trans gone through...

I've had a 3550 and now a TKO500 in my Cougar. Both had a bad backup switch that I had to replace. I can't be the only person who has had an issue with this switch (Google agrees). As a public service (and in case I lose the info), I'm posting alternate P/N's that can be found at ordinary auto...

For sale - Tremec 3550. It's been a good trans, but I upgraded to TKO 600. If you're buying for around town use - it's good to go. If you're buying for track use you'll probably want to freshen it up. The downshift from 4th to 3rd sticks, and sometimes it slips out of 3rd if not fully engaged...
