well i think ive finally come to the conclusion that the shiftplus was messing with my trans and causing it to slip between 1-2 gears. I first noticed after i truned my shiftplus off after being on for like 3 months straight. Anything over 3,000 RPMS when shifting betwen 1-2 would cause a slip. I also had some weird stuttering problems in the transmission when changing gears and low RPMS after some hard driving. Well i decided to take it easy on the trans. I turned off the shiftplus and drove semi normally. You what ive noticed? The longer ive been driving the less the trans has been slipping. I can now get up to 5,500 RPMS in the 1-2 gear without it slipping. And everyday i drive with the shiftplus off, it gets better and better. Now my trans shifts pretty much stock, ill give it a few more months and i think it will be back to normal. Meaning i can burry the needle at redline and the trans wont slip at all in 1-2 shift.
