I have been having problems with WOT shifting. For some reason my truck wont shift out of 1st or 2nd under WOT. I am commanding it to **** at 43 MPh, and 4400 RPM's. It will hit the rev limiter every time at 7200 RPM's at 55 MPH. I have tried lowering the MPH and RPM with no difference. This also happens when it shifts out of 2nd. I command 74 MPH at 4600 RPM's, and it is shifting at 7200 RPM's at 92 MPH. I initially wanted it ot shift at about 66-6800, and the RPM lowering doesnt help. Any suggestions? It seems someone else on here had this problem, but I couldnt find it with a search.

 

This might be your problem. It needs to change gears...



Okay, so I'm just being an ***. Somebody had to do it.

 

Ha ha I didn't notice that typo.

 

I just wish I had an answer to your question to go along with the smartass remark... best of luck

 

What table are you commanding this in? Part throttle, full throttle, all?

 

All of it. It will shift if I quickly let off the throttle, but not if I stay into it.

 

i had a problem with mine doing the same thing. I would do logs and it would hit the rev limiter every time. From my logs it needed to shift at 45mph to match the rpm i wanted to shift at. I had to eventually drop my mph down to like 36 before it would even shift out right. Could you post your tune?

 

Here is a link to my tune. Post 40. I can get you one that is in it right now after work. It is basically the smae thing except i lowered the MPH, and RPM quite a bit without any changes.

Oh man, I forgot to change D0910, and D0911.
.

Thanks to all that looked.

 

Is all well now?
