Gearbox identification

Hi Guys more daft questions on my new truck


it was sold to me as having a C6 auto, not that I care to much. I was under the truck all weekend waxoiling it, and though I should check it out.


The Box is one piece smooth alloy construction apart from the very rear where the speedo drive is, that's steel.


the only numbers I can see are cast into the bell housing are
RF08TP
7A040A
W2 XXXX (cant read them)


if this is a C6 what is it better to have than the cuise-o-matic?


thanks for the help


Barry

This casting number doesn't make any sense. F0 would be 1990. 8TP = I haven't a clue, since the prefix (minus the R) contains 4 digits. F8TP = 1998 truck, F0TP = 1990 truck.

C6 has 17 trans pan bolt holes, but if your truck has an FE engine, you need one that is specific to these engines only, that doesn't exist after 1976.

The C6 3 speed automatic transmission is considered more robust than the other COM gearboxes. It does suck up more power to run than some of the alternatives, but most people would be pleased to have it. It was introduced in some cars in 1966 model year, later in trucks. As ND said, count the transmission pan bolt holes and report back the number. NDcan then tell you which gearbox you have.
