2005 300c doesn't shift normal predator may have done this

[300cboy2005]

I have 2005 300c 5.7 liter I was using the u7135 predator I had it on 93 cai with the shift points at 6000 rpm the shift firmness increased the egr turned off and I put a 180 tstat and lowered the temp. I was driving in the highway after I got off I drove for about a mile I was at a stop light when I went to press on the gas it wouldn't shift right it felt like the tranny wouldn't grab the gears. It kept jerking this only happens in 1st and 2nd gears. I stopped driving it fir a week then I took it out after I returned it to stock and I unpluged the battery and put it back in. So it was fine for about 10 miles then it started doing the same thing agian so I went back home and when I was almost there I was at a stop sign and the car turned off and the oil light flashed but I chrcked the oil and it was fine

Can anybody help me?

so it does the same thing with the stock tune?
If so, it is an issue the dealer should be able to fix.
They will not know you had a tune in the car.

Eah it does the same with a stock tune just not as bad and it takes about 15 min till it starts. Have you heard about things like this happening to other people with the same car

just return to stock tune b-4 bringing into the stealership...and don't forget to reset the quick adjusts too! Have you ever had the transmission fluid serviced? These cars do funny things if the trans fluid is either low or high. The fluid has to be just in the sweet spot as far as fill level is concerned.
