98 GTP trans shutter

so sometimes when i hit the accelerator and its about to shift from first to second... the trans will shutter and feel like its slipping. Ive got a DHP V1.0 computer hooked up and that boosted the trans pressure and that seemed to help but now its starting to do it again... Whats wrong and how can i fix it?

Re: 98 GTP trans shutter

It would be helpful to post your mileage.

Any SES/CEL light? Some tranny slippage and pressure control related DTCs may be stored even without a SES/CEL light setting. I would get it scanned with a trans capable scanner. When was the last tranny service - ATF and screen filter?

Re: 98 GTP trans shutter

That doesn't sound good. Look at and smell the fluid if it smells burnt than you probably have some internal damage and just putting in a shift kit will only temporarily mask the problem.
