I want to install a 2400 stall lockup convertor on my TH-350. So far the best information that I have is that my trany is NOT a TH-350C. As I understand it this trany would have controlled the lockup on the TC.

I am willing to bet that I currently have a non-lockup TC because the trany came out of a chevelle. However it doesn't currently bother me driving it on the street, but better performance is always welcome. I am assuming that when I install a higher stall speed convertor w/ the non-lockup that street driveing will begin to be a problem.

The root of my first question is "How to install a Lockup TC on my trany?".

The second question if it isn't possible OR not cost effective is "Would it be worth it to keep the non-lockup setup and go with the higher stall or keep the stock (1400ish) stall in the car and not fool with it?"

Well, you've brought this up on several topics, but just in case it hasn't sunk in yet, you need a tranny originally built as a TH350C to ever have torque convertor lockup capability.

Never mind this question. I have been informed that this is not feasible w/out the TH350C version which I dont have.
