Another trans issue

[SuperDaveGSE]

So i got a used trans that was rebuilt recently, it was from a 99 Intrigue so the trans is a 3.05 gear set. My GS is tuned for 3.29's, I emailed Dave at triple edge. He assured me that if I swap my HD diff onto the LS trans it would then make it a 3.29 final drive ratio. Fast forward I get the trans in and fill all the fluids. I then start the car and run it through the gears to make sure the fluid circulates. That when i notice the problem, reverse isn't there. i have to give it a lot of gas to get it going in reverse. Then in drive, say from a stop sign I'll get it going then let off, it'll feel like its still in 1st and nose dive then slam. Anyone, ideas?

How'd the fluid look in it before?

did you have to remove or loosen the range switch below the shift arm? possible you need to adjust it. see if it starts up in neutral and park and the dash indicator is correct all the way to manual 1st/L
did you check the fluid level running in park on level ground?

Before I put in a new filter the fluid that was in it was very red/pink. I did swap over my range selector box on the trans, that was the first thing I adjusted when I noticed the problem. Each gear I put the trans into was correct on the dash. I ended up adding 8 qts into the trans total bringing it up to level.

Is this with the fluid warm? Does it work when cold?

I have a transmission in my shop that had an issue where reverse didn't work when warm.

Wait so its fixed after ading fluid? IIRC the total on these cars are 8-11 not counting the convertor

No this is a used rebuilt trans, the problem is there no matter the operating temp cold/warm.

sounds like input clutch seals and possibly the reverse servo seals if they are both the old short lip design
reverse could also be the servo pin not engaging the band slot from a hasty rebuild.
the reverse can be fixed in car with the rear manifold removed if its the seals or pin/band.

the input clutch issue is something i think hk's car has from a worn drum sealing surface

Turned out the two smaller hard lines going to the shift accumulator were mixed up. Oh well.... Shifts great now.
