Thread: PCM, transmission lag?

Well I just put in a new PCM. Its the basic one that most people get. it seems that when I'm not under WOT the transmission works fine. Shifts at the new rev limiter of 6,000 or so. but when normal driving when it shifts it kind of hangs or lags. Any idea?

Basic pcm that most people get? Which one is that?

Alright, I thought it could be that it needs to learn them. One other thing though is that it threw a check engine light, I used are scan tool to try and get the code but when I plug it in it does nothing. The tool does not turn on. I know the tool works (or did, its brand new) and I know my port on the car worked as I used it when I first got it.

alright, changed out PCM to old computer and it doesn't have the check engine light but the port still doesn't work. I'm guessing this is a fuse thats burt out. I went through and tested all my fuses in the fuse panel but I guess I missed one.....

I'm going to wait until I have a my down pipe on and my 3.4" pulley. I also need my aeroforce gauge to watch KR and if I have i still I'll put a plog on the front

I have to get a pcm for my 00 gt cuz its shot, but i cant get a Dhp yet cuz it wont pass emissions next month. Im curious where did you get yours?

I bought mine from another member on here.
