Not really sure whether to post this in here or in the trans forum, but here goes anyway...

I'm currently in the process of swapping out the old LO3 in my '91 RS for a carbed 350, so the computer will be going. I found 2 lockup kits for the trans, one being Summit Part # PRF-60109 ($124.95) and the other being Summit Part # TCI-376600 ($76.95). I was wondering why there's such a large difference in price, and what the fundamental differences in the kits are. I'm also curious about which one you guys recommend for the job.

Thanks in advance!

 

My situation was a little different, BUT:

When I was looking at swapping a 700R4 into my older chevy truck, I looked at the same kits. However, my tranny builder told me that he could set the tranny up to do this by itself, internally. I guess it's a very common thing for street-rodders and such. My builder told me that it was much better for the tranny and worked a LOT better than those add-on kits.

Might want to try calling a couple local tranny shops just to see if they could do it and/or how much $$$

Good luck!!

Thanks, Don....

anyone else?

 

i have the TCI-376600 on my car and i haven't had a problem with it at all. it feels like its computer controled but its not :-D

 

Here is what you gotta do... KEEP THE STOCK COMPUTER!!!

It will still keep the tranny working normally, and it will still try to read all the sensors you had going, but none will be there. It will constantly read an error code and display the "Service engine Soon" light. Just remove that light from your cluster and you are good to go... there is nothing that the computer can find wring with your new engine, so you are better off just junking the dummy light.

 

Try here www.700r4.com they have a nice kit that I have not had a problem with and it is cheaper than the rest.

 

IMO its better to junk the computer but thats IMO

 

From a theoretical standpoint, yes. however, allthought he computer is 'trying' to perform all kinds of extra fuctions, and the fact that the motor is no longer under any type of control from it, makes it moot. There is absolutely no adverse side effects to continue running the stock computer (with the service engine soon buld removed) with a carbed engine. It makes the job that much easier.
