Default TC slipping?

I hooked up a scanner and found that my TC slip reading is anywhere from 1600+ to 2200+, dont read any SES codes, is this normal or bad?

also says my shift times are around .60 to .70, is that ok or bad?


The reason I hooked up that scanner is because I noticed that that car is running slower and I don't break traction anymore, even in water.

That reading may be normal depending on when its ocuring and what stall you have , wether its locked up or not and what the driving conditions , SPEED ETC the data eading for the tcc look like idle running , The shift times are ok how does the shift feel? When looking at a data stream its hard to say whats right and wrong without knowing what the cars doing or how its being driven during the test.

fair enough.

Stock TC, tranny temp is around 150F, 1600+ occurs during light to moderate throttle, 2200-3000+ during wot. At idle, and when cruising, there is -3 to 5rpm slip, on deceleration slip is usually around -700 once it was over -900.

During light acceleration the shifts take .05 to .07, under WOT seems to be more .65 to over .70 The shifts feel pretty soft compared to what it was before, the 1-2 shift used to put me back in the seat and now is only a mild bump. From a dig the car wont spin the tires at all and seems to bog down before really moving. The reason I was even checking this is because I race a car I had previously beat by 5+ cars and only won by 1/2 car and only got that the top end of the track, I was playing catch up the whole time.

Well though its still hard to say the numbers dont look bad overall , But without actually feeling the car its still kinda a guess , the cruising slip is right on target as are the decell numbers , The moderate numbers look good too , I have never actually watched the percentage of slip at WOT so I cant really say there .
The bog however sounds like a running problem since looking at the numbers I cant really see anything that would acount for that , Is torque management turned off ?
also you may want to look at the TPS signal and see how it looks compared to your actual throttle opening

Torque managment is not off. Long term fuel is 10.1 short term is pretty steady 3.2 and is 6.7 at times. didnt think to check and see how much timing is being pulled during shifts.

I would disable that see how everything feels then decide if you want it or not
