C6 TRANNY

I have three questions:

1. When checking the tranny fluid, should it be running?

2. Should the tranny be in neutral or park?

3. What is the type of fluid I should put in it if it needs it?

Merry Christmas everyone! Todd

The motor should be running and in park. If start mine cold I like to shift into drive and reverse before putting it back into park and checking the fluid. This ensures all the needed fluid is sucked back up into the working parts after draining into the sump overnight.

If your trans hasn't been rebuilt I would suggest F-type fluid, if it has then Dex III is fine.

Thoroughly warm it up and check it, with the engine running, in park or neutral. Type F is the stuff you need to use. Did they change the clutch composition to use Dextron?

Dexron contains friction modifiers that make it less "grippy". Use Type F for more positive shifts.

Don't mean to hijack a thread or anything, but the topic is up so I thought I might ask a quick question:

Should shifting into Drive feel immediate? With my C6, if I shift into drive (brakes off), it takes a good 2-3 seconds or so to engage and begin driving forward (if no gas is given). I'm thinking that it isn't in good health...
