Transmission Shifting Wrong - Check engine codes displayed

[Lonestar]

Hey guys I need a little help. I have a 97 4.0 auto tranny and the check engine light went on. The code's read
P0700 - Transmission control system Malfunction
P0705 - Transmission Range Sensor Circuit Malfunction (PRNDL Input)
P0753 - Gear 5 Incorect Ratio

When I drive it it seems like it is enguaging the transmision at the wrong times and has a hrd time shifting into OD on the Hwy.


Any suggestions... Need more info?

Thanks

Any help? Also to add to my problem. I just overheated on the way back from lunch.... First time Ever. My guess is that the tranny is overworking the engine? or maybe another problem...[addsig]

The tranny overheating could transfer a lot of heat to the radiator. Your problem is over my head. I know more about manuals :-? [addsig]

i had similar problem on 98 gc it was the output speed sensor. it cost about $25.00 at the dealership.

The first 2 codes can either be a wiring or controller problem. That last one indicates slippage in the commanded gear. I would chase the first 2 and hope the transmission lived. Check all your wiring to the trans. And controller. I can look up a diag chart when I get home tommorow
