I did a search and could not find how to keep trans in 4th gear and not down shift at low RPM? I know this was talked about a long time ago.

 

USE THE MANUAL !

 

I assume you mean run the trans in manual mode, this does not keep it from down shifting below 3800 RPM.

 

If you dyno on a load base dyno . You can run it in third . You can get to WOT by 3200rpm with out it down shifting . We do use manual , but it will still down shift

 

Mine never downshifts at WOT

You must be doing something else than a standard DYNO run, I'm lost...

Try putting the car in third and get the rpm's at around 1500 to 2000rpm's . Then floor it without hesitation....it will down shift . If it doesnt..there is some thing wrong.

 

In automatic it does immediately, but if I'm in manual, it doesn't...

try it first, i know it does that on many other manual-auto cars..

 

Mine doesn't downshift at WOT. But there are several different versions of the tranny programming for different years.

 

I dyno my car like that, so I know for sure it doesn't...

Maybe it has something to do with the different Valvebodies ....

 

I had my trans program re-done by dealer and old and new program cause it to down shift at low RPM in manual. I was not able to tune below 3500 before which made car slugish of the line. I have the E-manage ultimate now and want the best tune I can get!
