Delay between 1st and 2nd after transmission rebuild..

[turquise1]

Hey ppl,

I rebuilt my ZF5HP24 this year in spring and finally got a chance to test it (I was rebuilding other parts of engine afterwards). Before the rebuild there was a big delay engaging 1st gear and that is fixed for sure. I thought it was all fixed until I got a chance to drive a little. Now, I have delay between 1st and 2nd gears. If I am driving fully automatic, car does not seem to engage 2nd (after 1st) properly but if I put on 1st directly and switch to 2nd, it switches and I can drive without problems.

I had rebuilt the valvebody before the transmission but the solenoids were never changed (tested ok).

What would be the problem? I know gears 1 - 4 are under Clutch A so that cannot be. I see 'E' brake engages at 2nd though. I am really hoping not to open up the transmission once again..


I have switched transmission computers and cleared adaptations as well..


Any ideas?.

Thanks,

Ozzie
