l know this is the stupid way that GM designed their transmissions, but is there anyway around this thats free, or atleast fairly inexpensive thats doesnt require chip burning?

thanks in advance

 

B&M has a nice little part that cures this. #70237 and is $34 from Jegs. The car I have had it and a 2200 stall Corvette convertor installed in the early 90's. But with the 2.77 rear end, I've never had the room to test it out.

86 T/A 5.0 A4 & 2.77 gear
15.62 @ 86 mph
93 Civic 1.6L
13.5 @ 100 mph

 

That part (the Throttle Plunger) doesn't always do what people want. The correct part is the Police package 3-4 TV Valve Assy. If you find a good Chevy dealer they should be able to come up with a number for you. No it isn't free though.

 

The GM part no. is 8673948. If you do install this part you will have to recalibrate the governor and the 3-4 shift timing spring because it will go into overdrive to early and bog down the motor.
