I would normally think this was not a tune issue. The only reason I do is the log shows the D4 selection but commanding gear 3. The transmission is the original transmission just rebuilt. ...
Anyone? The drive back home for the customer it went back into 4th!!!!!!!!!!!!!!!!!!!!
Then he drove it this morning and back to 3rd and no 4th shift. Any ideas?
Yeah I had fixed that already it is at .7499. I had actually moved it to see if it did anything (of course it didn't). But I know someone has seen this before. the tune says it should be in 4th. ...
Okay I know I am missing something.
Customer did a 5.3 to 6.0 swap all stock. The truck will not automatically shift to 4th gear. It was for about 3-4 weeks and all of the sudden no 4th. I rode...

Since I have never seen one I didn't know...
Any Help?
Okay,
Have a customers car 2007 GT500. Looking to see if switching to HP will be better. The car is currently trying to be tuned on SCT and the tuner cannot get it to go WOT (any boost) it just...
So pins 28 to 6 and 27 to 14. Thanks.

Okay,
Strange one and need some assistance. Have a 1957 Chevy that showed up (total Show Car!) the engine was installed with a Street and Performance Harness and ECM. The ECM is a 12597121 E38. ...
