Default Possible serious transmission issue?

At 67K miles I opened the tranny up and installed an HD2 shift kit with 1 washer and corvette servo's.. the tranny fluid was pretty god damn nasty. It was black with a maroon tint to it.

After all was said and done the truck ran great for like 2 days. I wasn't flooring it I was babying it to allow everything to break in and get seated correctly.

Anyway... tonight I put it in reverse and it went no where I gave a light tap on the gas pedal and the truck made a slight jerk and then rolled on backwards by itself as normal..


And now... rolling off the line from 0 the RPM's will come up as normal and instead of giving me a nice aggrive crisp shift into 2nd gear.. the rpm's will come up a little and then jump up and come back down real quick giving me a sloppy shift into 2nd. For the rpm's that its at while going through first gear I should be having alot more power then I'm putting down.

All the other gears are fine. Once I'm rolling the truck runs fine.


Any idea's!?!?!?????

If the old fluid looked that bad I would say you have some burnt/worn bands/clutches.

but to notice these issues now?

and what exactly causes the RPM's to jump up like that when I'm not giving it any extra gas? its like someone else is accelerating


the fluid seems about an inch maybe 1.5" past the crosshatch area. and as previously said.. downshifts/upshifts in other gears all appear normal. its that first initial just past rolling off the line.

and as for the old fluid when I initially dropped the pan and started cleaning everything there was clutch material on that little magnet...

CHeck ***** are in and in the correct positions. I know this because I got one of the chevy guys at the dealer print me off like 30 pages on how to assemble the 60e..

are you referring to the washer on the 2nd accum? what would that do?

screens on the sep plate.. are you referring to the gaskets? If so.. then no I didn't reuse those. I used the new ones that came in the hd2 kit.


new filter installed and inplace correctly.

fluid is over filled by about an inch-two inch past the crosshatch area. That wouldn't cause this though would it?
