No Reverse

[1duffman]

Thanks for all the info farmtruc. But a converter question now, I'm lookin around online and have found GM81 and GM82 converters and have no idea what the differance between the 2 is. This will be the first I've really delt with torque converters, always had one for the 60E



Edit: Found out with some research GM81 is low stall and GM82 is high stall no sur of the stall speed but I'll research that too

The high stall part number isn't much higher but every little bit helps. I think one is around 1800 and the other 2100rpms if I Rememeber correctly. Been a long time since we bought one.

Earlier I said "basically stock set up". My enigine is basically stock but I put som 806 heads on it. I've been wondering what my CR is with everything stock (gasket thickness, compression height, and no shave on the heads). Then I was wondering how they would affect my torque curve and about where they moved it to. I just graduated college for auto so i kinda feel like a dumbass askin all these questions but there is still alot I don't know.



Sorry their 862 heads...

As far as a converter goes, even a low stalling aftermarket will be a LOT better. The stocker is so damn heavy. Anyway, keep a watch on a few forums classifieds, used ones come up fairly often. Likely find something cheaper and better than a stocker

Will do!!!

Did you remember the reverse checkball that goes next to the accumulator in the case? There's a few things you could check without pulling it out. Also you can drop the VB and air check the reverse piston to make sure you didn't fudge up one of the 3 seals. I'm a trans guy, new to this site but anything you need to know or ask just let me know.

Reverse is purely hydraulic, no electrical troubleshooting is going to help you. No matter what, it's gonna have to come back out. Before you pull it, drive in the parking lot in manual low. Tach it up to around 2500 and let off the gas. If it has engine braking, the reverse input clutches are not applying... Or the reaction shell is broken/ stripped. If it doesn't have engine breaking, the low/reverse clutches aren't applying. Either way, no reverse = pull it back out. No sense in dreading it, it has to be done.
