What RPM is your car Idling at now? Also you can unplug the Vacuum Advance and plug the hose, to check if your advance is messing you up..You know, take it out of the picture before you go and start to change things

I just read something about a problem with cars stalling in drive and reverse because the TCC is engaged.

A snap-ring being upside down ---- converter clutch apply valve snap ring in backwards

rounded edge installed facing inside to the valve..flat edge facing outside away from valve

He has a non-lockup TC in his car. But you are right, an engaging TCC will stall the engine.

On a budget, try a V6 TC. Mine stalls to 2800rpm behind a bone stock Vortec 350. But much better results will be had from a QUALITY aftermarket TC They arent cheap but you get what you pay for. Yank, Precision Industries.

Hog: what is the diameter of that V6 converter?

There is a a 4 letter/digit "K code" on the GM converters. what is the K Code on that GM V6 converter that created a 2800 stall?
What car did it come from?

Here is the PM I sent you F-Bird
The 4 digit alphanumeric code id DBLF. It is from a 1996_ L35 V6 S-10. It has the same guts as a 1986+ Vette converter, just a different TCC damper assembly. GM p/n 24202310
Its a stock 298mm 11 3/4" unit

I'm glad you asked me about this as I have been calling it a DCLF which doesnt exist, its DBLF

If you are using this on a 1995+ vehicle use the matching year V6 S-10. Pretty sure the Vortce Blazer/Jimmy V6 TCs are the same. I got mine for free. If doing an 86-1994 use the corresponding year Vette TC.

More info here. These guys say it stalls to 2200rpm nbehind a stock 260hp iron head LT1 which uses teh same cam as my stock longblock Vortec 350, but when I apply the ebrake and service brake and quickly go to WOT my tach reads 2700-2900rpm at WOT. I had a PCM tune, LT heads air intake. The truck ran a 15.9@ low 80mph with 2.5 60 fts, now runs 14.8'sat 92-94mph cutting 2.00 60fts. Not bad for a stock Vortec 350. I never got to the strip with the L35 V6 TC and marine intake manifold on it, probably low 14's now.

Dacco lists & sells a B-29DCLF converter that supposedly stalls at 2100RPM. That is just a range and it will probably stall higher, or lower, in different vehicles with different weights, or different amount of torque production.

In the B-85 line there is a VJCX which everyone calls the "Trailblazer SS" converter and it too stalls around 2100 as per the box. These, I believe, are the highest stall converters you can get without going to a smaller diameter body such as the 10" B-24 as used in the 4 cyl. S-10.

If you want a higher stall than the 2100, and you are running a 4L60E/700R4 then Dacco will sell you whatever stall range you want in the 10" B-24 converter body, and will custom make the converter for your requested stall speed. Prices start at $395 locally, but should be close from any Dacco supplier nationwide.

i have an 'off the shelf' Daaco 2500 stall lock up converter in my 700r4.. I Love it. it's a very 'tight' converter.. so it drives like a stock converter if I'm just cruising.. but when I punch it from a stand still I can feel the stall :>

Its kinda weird that peoplel call that TC a "Trailblazer SS" TC because a TC from a TBSS wont fit any pre 1999 4l60e's. It would only fit behind engines that are GEN 3/4 4.8,5.3,5.6 and 6.0 l engines.

If you want a higher stalling TC in a vehicle that has a GEN 3 or GEN 4 engine, you need to use the Trailblazer 4.2l Inline 6 TC. It stalls to about 2900rpm behind the bigger 5.3/6.0 V8's. If you used an actual TC that came from a Trailblazer SS 6.0 behind a 4.8, you would actually have a lower stall speed.

Here is the link to the Alphanumeric k codes, as I see my above link is dead.
the highest stall TC from GM that works in the GEN 1(TBI,carb), 1E(Vortec305/350) and GEN 2(LT1/4, L99 4.3 V8) th700r4/60/60e/65e/70e is the DBLF L35 4.3 V6 TC, which has the same guts as the 1986+ Vette TC except it has a different TCC damper.
THE HERD: Torque Converter Upgrade
I can brakestall this TC to around 2800rpm behind a stock Vortec 350 which is rated at 330 lb/ft at 2800rpm, but I'm outputting more than that now.
The good thing about the stock DBLF L35 S-10 95+ and the DBCF(86+ vette) is that they are effecient. Lower cost aftermarket TC's get into bending fins to change stall speed, this causes the TC to be less inefficient. You get what you pay for. COmpanies like precision Inudstries, Yank and CIrcle D make strong efficient TC's but you will pay for them.
