Need HELP..... Tranny or converter or electrical problems?

[texasstroker]

Just bought a 97 F-350, 7.3L Powerstroke, auto od trans.

Went to drive it and it seems like it is starting out in 2nd or 3rd gear and when I messing with the od button it act as if the converter is trying to lock up or unlock and makes the engine stall out.

What do I need to check?

I'm guessing you've checked the trans fluid. Still red and full?

Yeap, did that first thing after I started the truck. Looks good and not really any smell other than ATF smell.

The back I am buying from will let me start them and put them in gear but nothing else. The lot was packed full of repos and trucks parked bumper to bumper so there is no way to really move around. Have bought a bunch from them and all has been fine so far, guess I will get a bad one ever now and then.

Truck is at the shop now trying to check for codes first.

We hooked the scanner up and the first code was speed sensor and the 2nd code was something called gear range selector sensor (mounted on the side of tranny). So we are changing the speed senor first since it is just a $23.00 part and see what happens.

If not we will be jumping in the the other sensor which is a dealer item only and my cost is around $80 bucks.

I have never hear of this before causing tranny problems, but the tech at the dealer tells me they are famous for it.

The gear range selector sensor is adjustable, if you watch the data on the scanner and move it you should be able to get it in the right position.

the E4OD is a VERY computerized trans, and it need a lot of input to run right. a bad speed sensor will make it shift bad
