I just called a guy w a boat.
He thought he had a bravo w an auto tranny but the boat was from 1987, and I'm figuring it was a TRS from what he told me, but he is SURE there is a T400 tranny behind it.
Is it possible to put a Turbo 400 tranny into a TRS drive?

Thanks
Evan

I've been told they are Ford trannys. One guy said it's a C6, and another one said it's a FMX. I'm leaning towards the FMX tranny.

What is an FMX?

some are mercmatics (in some ways similar to a ford c6), the other are borg warner (72)

merctrans or Borg warner ..borgs were better supposedly. I never spit out a merctrans.

The Fmx transmission was between a C4 and a C6.

The MercTrans was made by Mercury. They use some Ford components like plates etc. The weak link was the pump gear. They have a tendency to split at the keyway. For lower hp applications (400 or less) they work just fine.

Cuda,the fmx was actually a 3 speed version of the old 2 speed ford cruisematic.It was fords "cheap" transmission they put in base model cars with v-8's.It was a carry over from the 50's. You can tell when you see one because it has a cast iron mid-section. There is a C5 between the C4 and C6,it is just a heavy duty C4 that was used in trucks mainly,and all 3 of the C transmissions used a aluminum case,Smitty

I don't know if th-400's were ever used with a trs but I have seen them in v-drive boats,they use a considerable amount of hp to turn (around 60),Smitty

But what was stock w TRS?
there was a Mercruiser tranny and another one, what was that?
