I have a 2006 SRT8 with a NAG1, HRT Stage 3 cam setup and a FTI 3200 Stall Converter.
I am currently having an issue getting this d*** thing to grab fourth. I have tried so many different things, raised TCC slip offset, tcc rpm, unlock converter 1-3.....etc....
1-3 it acts decent, once it shifts to fourth its like it punts it right back out of gear and into limp mode.
Fluid level is proper, checked with B&M dipstick, pan filter and gasket are less than 1k miles old and trans pan wasn't super contaminated with wear.
I've had this car about 3500 miles and it was fine up until doing this cam swap with the converter.
I have also removed the valve body connector plug and sprayed it out on the trans and harness with electrical contact spray with compressed air to follow up, no change, thinking that it may have had a contamination issue during the trans removal.
Attached below are the files,
this car isn't done being tuned for the cam or anything, this is pretty much where I am stuck.
