Hey guys. I'm building a 700R4 for some light duty racing and am in need of a torque converter. I was looking for a 3000 stall and lockup for the street. I was told be a guy who supposedly builds trannys that you wouldn't want to do that because the lockup clutch would be so small at the 3000 stall range that you would burn it up very quickly. I understand the idea behind this but what do you guys think?

 

Judging by the info in your sig., 3000 stall would probably work pretty good. If you want to retain your lockup feature, you shouldn't scrimp on the converter you buy. Although they're really pricey, I'd highly recommend getting a Vigilante, Yank, or Edge converter. If you buy a cheaper, off-brand one, it'll be a big disappointment. The above mentioned companies will also re-stall it for you if you end up needing more or less stall speed.

 

That's what I'm hearing. The torque converter is one of those "You get what you pay for" items. But on the subject of stall vs. lockup, is 3000 too much to keep the lockup?

 

3000 is pretty high for a lockup style converter and that's why I recommended one of the high-end ones. Most companies don't even make a lockup converter with that high of stall, but a Vigilante would definitely fit the bill. Hopefully someone who's running one will chime in on this post, but I've heard nothing but good things about them. You get the best of both worlds with them by being able to retain lockup features with a high stall. That's why they cost a lot. The cheaper ones make the same claims, but they really don't work that well. Bad experiences with the cheap ones is probably why that guy told you it's not possible.

 

cool. I'll have to do some shopping then. Thanx

 

I thought mwnova runs a 4000 stall with lockup in a 700R4... maybe i'm wrong..

 

im running a 3500stall from fuddle racing it was 500bux to my door comes with a carbon metalic clutch and it works just fine. just dont cheap out on the converter it is the link between your engine and your trans.

 

What manufactures do you suggest? I've heard to stay away from B&M but really no resons. What do you guys suggest?

 

As stated above, I would stick with Vigilante, Edge. I've heard mixed reviews on Yank and Fuddle. Def stay away from B&M and TCI I am running a 9.5" Street Edge 3600 w/ 2.45 STR and lockup. I've had it in since saturday and I love it. I am already use to the drivability of it. Andre is a great guy too!

 

One of the member recommende a TCI for my 700R4. Why do you say to stay away from them?

 

B&M and TCI both built up a good name providing performance parts for the old TH350 and TH400 automatics. The 700r4 trans is an entirely different animal from the earlier models, and those two companies aren't really up to par with the parts they offer for the newer autos. I'm not even sure if Precision Industries (Vigilante Converters) even existed before the newer autos came out, so they basically built their reputation on the newer ones. In fact, I hate to say it, but B&M and TCI rely so much on brand recognition to sell their parts, that I personally feel their customer service and quality control has gone way downhill in the last 10-15 years, not to mention new research and development as well.
