700r4 lockup and stall convertors

While driving around this afternoon, I stopped at a place that rebuilds Tourque convertors.

The guys there were pretty friendly and informative.I got to tour their shop and see how T/C`s work,very interesting to say the least.

It`s amazing how simple they really are.

Anyway the guy told me that he will beat anyones price on all different rpm stall convertors including lockups.

He is currently in the negotiation process with a new supplier of furnace brazed rotors,stators and also other hardened and high performance components.

He told me that anyone who buys a convertor from him will get one free adjustment,which means if your not happy with the stall speed that you`ve chosen . you can ship it back to him and he will disassemble it change the turbin and adjust the stator blades(which controls the stall)reassemble and rebalance it.

In the next few months they are expanding into rebuilding cv shafts,and will be able to give deals on those also.

When I mentioned that I might be using a 700r4 in the Z, One of his tech`s told me that any 700r4 can be made to lock up manually(without electric) He said if you cut all the wires,remove the lockup solenoid and install a check ball under it the t/c will automatically lockup when you hit o/d and the fluid pressure hits 50 psi. He didn`t say exactly what diameter but I`ll post when I talk to him again.

That means that there is no nead for elec relays, wires,brake switches or toggle switches.

You learn somthing new everyday 2thumbs.gif At least I did, To some of you this may have been common knowledge ,but it`s news to me.

As soon as I get a price list I will post it. He said the more we buy the better deals he can make.

He said that he can build any grade of stall t/c from standard duty all the way up to the top of the line with all the goodies cheers.gif

Please , keep everyone posted on this check ball to lock-up the overdrive on a 700R4 without electric wiring and solenoid.And please find out if the same modification will lock-up the overdrive in a 2004R.

i love those 700r4s, nice low first gear in those things, and when they are built up, oh man the joy, i have a 87 firebird with the 305 with a vette servoed 700r4 and a slightly higher stall in it, man this barge will fishtail and smoke posi for almost half a block by just hitting it wot from a stop, and get fistail second if i stomp on it from a roll, some of the only joys i get from that car at all, since i lose every race i try to engage in in that thing.

They are just south of town off of 431 on the right. I`m not sure if they have the new catalogs for t/c components yet.When I talked to them last week they were waiting on some more liturature
