Automatic transmission

Xoloanon

Mitch does you auto tranny have anything here where I circles in the pictures?

Xoloanon I'm laying under the truck and mine is so caked up with crap like old oil and mud it's hard to tell but it does look like yours.

My exhaust is in the way and I cannot get in there to get a good photo.

Xoloanon That's where the trans oil pressure switch goes IF equipped.

Oil pressure switch in my 92 B2600i rear drive.

What is it saying that is? A line?

MazdaMitch

Xoloanon have you looked at this?
Tons of information.

Awhile back I looked at it pretty good and could find it. Just looked again and still can’t tell what it’s suppose to be. The hole is smooth with no threads with a small hole in the back of it.

Xoloanon I'll know more when I pull this auto trans from the truck to clean it up.

It may be a while though.

Xoloanon......can you take some pictures of your auto transmission crossmember and surrounding area and post them here? I would like to see how that crossmember is installed, since Mitch is wondering what the best way to pull his engine and trans.

Xoloanon

Looks like that piece on the front of the crossmember will unbolt and the transmission could drop straight down.

Hole in my transmission is smooth with no threads. Maybe it’s not equipped it and that’s a blank put in place? Where would the other end plug into?

Xoloanon The oil pressure switch has a 1 pin connector that connects to the engine harness. The engine harness connects to the front harness near the under hood fuse block and then goes to the TCU in the driver's kick panel.

My 91 B2200 (fuel injected) has a TCU with 12 pin connector. It does not have the oil pressure switch on the transmission.

This is the TCU 14 pin connector in my 92 B2600i rear drive.

MazdaMitch I know on the manual the one is reverse but what's the other for? I'd like to take mine off my reverse lights are part of my brake lights so no need?
