I put a B&M shift kit in my 700R4 when I rebuilt this past week, and now my overdrive doesn't engage or apply, theres nothing there, its like going into neutral.I was thinking it could be the TV cable out of adjustment but not sure.Can anyone HELP ME please,need info

 

Did you have to do anything with the servo with the B&M kit?

There is a seal on the 3-4 apply piston that can cause what you are talking about. Happened to me when I switched servos, seal was pinched and I had no OD.

Sparks a flyin'

 

When you removed the spring from the mtv valve, did you put the valve in backwards?

The b&m doesn't have a servo kit with it.

It's the only thing I could think of...sorry. Hope it helps, but I guess going back through and checking it is the only way...

Also there's a small relief hole on the pan gasket rail from the servo area. Make sure the gasket doesn't cover it.

 

One, B&M doesn't make a Shift Kit.
Two, you likely tore the Teflon seal on the small piston that goes into the Servo Cover (BTDT).

 

They don't make a shift kit?

I WOULD RATHER PUSH A CAMARO THAN DRIVE AN IMPORT

1983Z28 350w/ edelbrock performer RPM power package with 64cc aluminum heads, dynomax shorty headers, 700R-4 with shift kit, 750cfm carb, edelbrock 3" exhaust system, ASCD SS hood, 16" IROC rims.

future mods:
completely done over suspension, black paint with flames, Hurst shifter, dakota digital gauge package, procharger supercharger.

 

HAHAHAHAHAHAHAHA!!!!! So those products that B&M markets as shift kits, those are really...placebos?

No wonder they suck.

 

Shift Kit is a registered trademark of TransGo. B&M makes shift improver kits. To call anything else a shift kit would be like having a Ford Camaro. To complain about a Shift Kit when it isn't one can give people the wrong impression.
