after a recent highway run, we noticed the o/d light flashing. Then the CEL came on.

Since I remembered I had my programer in the truck, I decided to pull the codes, and reset them.

This is what I got:

P0732 Gear 2 Incorrect ratio
P0735 Gear 5 Incorrect ratio
P0741 Torque Converter Clutch Circuit Performance or Stuck Off

After the reset, only the o/d light flashes now.

on highway speeds the rpms are approx 3100.

Any suggestions?

Should I look into fixing it? or putting her out to pasture?

Check the bulkhead connector on the internal wiring harness.

It's the wiring harness on the transmission for the internal electrical components.

Do a search on tsb 02-13-8. There's a lot of info on this here.

finally had time to look at wiring harness, looks fine.

What next?


A continuity tester has to used to check each wire from one end to the other on the internal wiring harness.
