Here's something I noticed while reading the Infiniti FSM. According to the text, the TCM raises the line pressure when the fluid temps is lower than "normal". Does that mean installing a big trans cooler will increase line pressure which speeds up shifting? Also, what temp. is considered "normal"?

I may be misunderstanding this, but doesn't that '5AT' on the top right imply that this might just be for the 5AT auto?

IMHO, line pressure is up to compensate for cold TF. Hot TF moves better in the lines.

I drive a 5AT G sedan so the FSM is differentiating between the 6MT and 5AT, rather than 5AT and 7AT. I'm assuming the same function is applied on the 7AT.
