So after a a successful B7TA rebuild in my 2000 odyssey with 255,000 miles on it...I thought hey, why not try a 5 speed.
Bought a 2001 Acura TL with 185,000 on it with a bad transmission for $500.
After reading acurazine it appears the current m7wa is a pre-2005 rebuild.
No oil-jet kit. Painted bolts on transmission. ATF fill port is 17mm. If I understand correctly, 22mm ATF fill bolt is an indicator of replacement after 2005.
On the bench teardown showed broken main shaft at 5th gear clutch pack.

4th gear has residue of 5th gear friction material that settled down into teeth of 4th gear.
Already have my parts for rebuild. Didn't realize the 06/07 AV6 or 05/06 oddy swap was an option or would have gone that route.
Plan to do the same thing I did with my odyssey. 1000 miles on odyssey rebuild. Buttery smooth. Running dexron lll with lubeguard for first 1000 or so, then plan on Maxlife synthetic per recommendations on odyclub.
m7wa will get:
Translab Superior VB kit
Transtar Master Kit
New TC
valve bores polished with bench buddy from superior
New internal filter
New external filter
New pressure switches
