I just bought a 2007 GC SRT-8...loving it so far.

Now I am reading some people talking about a TCM upgrade that is free from the dealer. Can someone fill me in about this? Is this something I can get for my new 2007 SRT?


Thanks.

The TSB says '05-'06. There is a good chance your '07 already had this problem solved at the factory.

The only problem my '07 TCM has is that it shifts from 1-2 at 6100 or 6200 rpm and I believe it then hits the rev limiter and has the hesitation or stumble. I believe that I will just get the stage II PCM from B&G as I do like everything else about the TCM.

I have the same problem as builderbill.

I am sure they will come out with a TSB to fix this problem.

I hope!!

I did get disappointed today in my '07 rolling at about 20mph with my cousin in the passenger seat and floored it and it did not kick down to first. Was a very depressing display as I wanted to throw him back in his seat and instead we just calmly accelerated away.

You would think that from any speed that the tranny would pull down to the most aggressive gear for acceleration. At 70mph on the highway it drops down nicely and pulls hard. From a slow 5-10mph roll it drops to first and pulls like a bear.
