I had a 99 Camaro until I totaled it last year.I put my drive train in a 2000 Trans Am.Here is the thing,I have a 3800 Vigilaunte Converter and this thing Hit freaking awesome from a roll Nose up Tires spinning,Now in this Trans am the converter Does not hit hard at all,In fact when I floor it feels like I am just blowing though the verter.The guy that did the motor swap told me the Vacuum modulator hose was melted though(Disconnected on the Camaro) and put a new line on the Trans Am.He said I was at full pressure all of the time.So why would my converter not hit hard now?Thanks

 

Is the rear gearing the same? That was the big thing I noticed between
the Z/28 I test-drove (2.73s) and the SS I bought (3.23s).

 

vaccuum modulator? Didn't know we had one? Seriously I don't remember any vaccuum lines.

 

No we don't unless your Trans guy put one in.I have one....

 

Jimmy ,my drive train is the same I have a Moser 12 bolt with 3.73 this was awesome in my Camaro but it sucks in the Bird.Should I try going to 100 max and 90 min in the TCC Duty Cycle?

 

Also you might try clamping the vacuum line and seeing if it has the old feeling, that way you know that is the variable and go from there.

 

Yes I have thought about it and I may try that...Thanks!

 

Let us know, I'm curious to see if that's the problem.

 

Well Mike13 thats what it is pulls like it used to with the vacuum line unplugged
