Strange At Check Light

[YangLIU]

hi,

Craig helped fitting transgo kit last year with Nulon full Synthetic Multi-Vehicle Auto Transmission Fluid and transmission filter.

1. on another day in that week, i got AT check once when try to stop at traffic light, when the car nearly stop, i feel a big "don" noise then AT check light on. i release brake then the AT check light off and i could continue stopping the car. (this is the first time AT check light on)

2. after near half year driving, AT check light never popup again until last month, i let JEZ tuned my car, also on another day in that week, i got same AT check with same situation as the first time. (this is the 2nd time AT check light on)

3. today, i curising on hwy with flat foot, also hear a big "don" noise (i didn't release my foot from acc pedal), then AT light is on and the tacho shows rev going high from 2000 to 5000, then i stop acc and AT light goes off and i could continue acc the car. (this is the 3rd time AT check on. i unpluged battery yesterday, not sure if they are related or not)

before fitted transgo kit, i never have AT problem

i checked the AT code via consult3 but nothing could be found. yes, that's after AT light off when i get home.

guys, any idea?

btw, i always drive in "D" and all AT check light on "D". and the big "don" noise is "clunk" sound.
