Finally figured out how to describe my trans issues with my spartan tunner
Curious is anyone else is experiencing this. I've seen other threads on the rev/slam. And that is definitely not my issue. My truck is basically trying to "flare" the 1-2 or the 2-2 shift when hard on the throttle running the 250 now. Now my concern is, its only done this since spartan updated its tuning files a few weeks ago. My truck is a job 1, and the fluid level is fine(i just drained the pan and changed filter about 6-7k ago).
Today leaving a stop light from a dead stop the truck took off, and when it went to shift 1-2 it flares and then BANG, it did this about 2 weeks ago getting on the freeway going from 2-3 also.
Im curious if im the only one having this issue, and if im not what is spartan doing to correct it?
Im away from home for a week, but when i get home i will check the fluid again, re-tune and re-learn, and if the problem is still there, the tuner is coming off. Im not risking a transmission over a stupid tuner.
