the other day I was drag racing, I had it in 2wd the first few times, lockup switch on and OD locked out. running down the track I get to the top of 3rd and hit the OD button, and it stays lit. the trans never shifted into OD either. it did this twice. so then I decide to leave the OD button alone. it works great then, but a few times when I ran it in 4wd, it wouldn't shift in to OD either. did I do something wrong or what? it seemed like it would shift into OD if I pushed the transfer case into 2, but there was a time I ran a great run in 4x4 and forgot to push it into 2 and it still went into OD. any one else have this? its the stock trans BTW.

 

The O/D switch is not shifting because of our tps. Mine freaks out when it wants too. I was just at the track last night and it would let me shift in to o/d two out of the three times I ran. I am pretty sure your tps needs adjusting. I have the same problem. I adjusted mine so it would shift into o/d at full throttle but then my converter lockup is all messed up. Not sure if I will ever win

 

get any good runs in? curious as to what times you ran

 

15.75 was my best time @ 83 mph not sure what Jambii ran

 

How hot was the tranny? I heard if it gets hot it wont go into overdrive.

 

never went over 150

 

LanceD did you run 15.75 with the big tires or swap out small smaller ones for the racing?

 

I had some little ones on. I think they are 30 inches or so
