[Shotimes] Redline D4 best fluid of choice for an MTX-IV with "paper" synchros

[Ron Childs]

My '91 came with ATF and it is specified in the owner's manual. Does this mean it has the new type synchros? I did not know that gear lube was specified for any SHO.

What I got out of this is the way BMW approached selection of transmission
fluid for their cars. One point being that from the factory they use an
ATF fluid. Ford could have done the same for our cars when the synchro
design change was made but didn't.
Anyone know if the 5-speed Getrag in the Lincoln LS uses ATF fluid? Just
curious.
