hi everybody,
I recently purchase a 2003 allroad 2.7t with few problems!
replace alternator,tensioner and belt plus re torque the valve covers for few oil leaks on the exaust manifolds.
I keep the big work for last!
I just remove the transmission for no reverse (d drum ).
I'm an auto mechanic in Colorado and I try to fix my reverse.

now I'm in trouble to find the parts.
I can find the d drum used on ebay , but I also need the reverse piston outer o-ring and the 3 rubber pieces inside the fluid passages for the pistons actuation.
I can't find it and I'm start to be worried.
also what color the reverse friction material should look like?
mine are black with no grooves , it is normal?
compare to the rest of the clutch packs they look yellow? gold with the grooves on it.
it is raccomended to do the rebuild kit since the tranny is in pieces?
and witch rebuild/overhaul kit do you guys suggest for price and quality/
thanks

Maybe not related, but definitely clean the valve body: Transmission Problems Transmission in Limp Mode - AudiWorld Forums

See my second link in previous post. Might help. I did not take the tranny off my car yet so can't help. Sorry!
