Hey guys-going down the road today for work(about 30miles into the trip) the tranny jumpes out of OD into 3 but when I stepped on the pedal the rpms shot up but not the speed, like it was slipping. this was at 70mph- I let of the pedal and it shifted back into OD and was fine for ten miles or so before it did it again. only for 5-10 seconds at a time. Let it sit for two hours or so and it was fine for about 80 miles with weight on it, highway and city. No change in acceleration even when I mash the pedal-still shifts smooth and quick. just wondering if it sounds like the tc or something else. Thanks

 

Hit the OD cancle button and see if lamp lights.
Did the OD lamp flash?

The second time I did hit the od cancel. When i engaged it againit hesitated and then shifted back to OD. No flashing light

 

But does it light up when you cancel it?

Bill

 

yes it did light

 

CEL?

Bill

 

no. It only happened twice but the second time I was watching\feeling for it. But no CEL. I forgot to add that it has a banks transmission controler on it. Been on for 4 months or so. That really tightened up the shift points.

 

The banks will raise line pressure. It fools the EPC.
Cannot really say anything about the issue.
I would recheck the command wiring though.
Just be shure the pins are locked into the connectors. Pull on the wire (each pin) to be shure they do not come out of the plastic housing.

And check all the brake lights. Just to be shure they work and they are not to sensitive to go on.

the transcommands I have seen have not been sealed well and actually crumbled in my hand!

 

Well I will keep driving it and watch it closely. If it does it tommorrow I have a bypass jumper for the transcommander. I will try that for now and see what happens.
