Ah. that makes sense. Figured it was something like that. I like the way the 99 shifts at part throttle with PS on better.

[/QUOTE]All you have to do is swap the trans line fittings into the 99 car if you are using a 99 radiator. If you swap the 2002 rad into the 99, then everything will be a bolt in. Then run the 99 PCM and you will off and running.[/QUOTE]


Got it. Thanks for the clarification, this is real helpful and now I know. The 02 rad may be damaged so this helps me plan.
