I have a 700r4 that I just took out to install a new higher stall converter and thought while I was at it I would hook up the lock-up too. It is in a 1961 Impala so I need a kit to do it as there is no computer.

My question is what one is a good one? It is street driven 99.9% of the time.


I think I want one that will just run regularly so I do not have to worry about turning it on and off all the time. Just not sure what ones are good as they all seem to have a different approach as to how they hook up in all the kits out there, as do all the do it yourself instructions.

Any help would be appreciated....

Thanks Grumpy some good reading there! although I am still a bit leary on wiring up my own.

Will it hurt the tranny If I do not run one as I only run the car around town? I could just maybe wire up power to the stock plug with a switch for if I ever do hit the hwy.

Any body running the TCI kit with a healthy cam? Just wondering with low vacuum if it still works well?

Or input on the B&M kit? Likes dislikes?
 
the torque converter generates a good deal more heat untill it locks up, so a trans cooler is a really good idea if its not set up to lock up, ID strongly suggest calling and talking to a MINIMUM of 4-5 of the transmission suppliers and ask ALOT of questions of each tech guy, befor deciding on your setup
 
Hey Grumpy, I have a good cooler already so I should be ok there. Question, If I have 12 hg vac at Idle will it be more or less at say 2000 rpm cruise in 4th? I have the tranny out now so testing vac at cruise before I hook up the lock up is out. Just wondering so I will know how the TCI kit may or may not work if I go that route. Here is what it says for the TCI vac switch.....


Q: What is the setting on the vacuum switch?
A: The vacuum switch comes factory preset to close at 8 - 10 inches of Hg. This
means that in order for the solenoid to be activated the switch must get 8 - 10 in.
Hg. or higher. If you find that the torque converter lockup experiences "busyness"
(shuttles on and off rapidly) at cruise conditions it is probably because your
engine vacuum under that particular condition is right where the switch turns on
and off. This can be verified with an engine vacuum gauge.
