82 with tc lockup problem
I finally fixed my code 42 esc problem.It needed a new computer,but the first one was bad sending me in other directions.Now after 2 months It is fixed,I also replaced the prom with an original updated gm one.Ok all is good.Before I replaced the computer It never told the tconverter when to engage.Never bothered me because I had it wired so I could force the lockup to engage when I wanted to.Now that I have the new computer when I drive very mellow It shifts from first to 2nd then locks up to fast then third followed by a fast lockup and forth the same.when I drive spirited the car drives good no lock up in 2nd or 3rd and 4th locks up above 40mph.I just want to put anoverride swich back in ,one that can turn off the lockup.I figure into the brake switch is the way to go.by the brake ther are 2 sets of wires a very thick set (heavy gauge) and a very thin pair.any Ideas which wires to splice into Thank u all forum members as always

thank you
Really want to thank everyone for there help.The purple wire did it.Still have to determine why the new gm chip causes the car to lock in 2nd and 3rd so early,or even why it locks up in second or third to begin with.It sounds like a good idea on paper but the computer is to slow to unlock when you give it a little gas once it is locked in second.Ideally the tranny should only lock up in forth,and unlock fast when u give it moderate gas.Any thoughts? but forum members thanks for all your input.I don't respond much to questions because I am not a pro on vettes even though I have had 14 in my life,all c1,s c2' and c3's.unless I know the exact answer I rather not give slipshot opinions.Now I have to rest my back fro going under the dash to get at that brake switch.Old vette owners just fade away. bless u

I believe the quick lock up is a fuel mileage trick used in the early days to lock the trans to eliminate slippage at the lower speeds, my '82 locks quickly in 2 & 3 with the OEM chip, an also with the hypertech.

The B&M lock up kit is not too expensive. The $ sign was a slip of keys.LOL
It may even pay for itself because of the improved gas mileage....
