Default What Torque Converter Do I Need?

Ok Im looking at getting a TC. They are both used. But im not sure what one is the one for me. I have never delt with a TC before. The car is my daily driver. I plan on putting a 3.42 rear in the car. I want to get rid of the slow reaction. But I dont want to over do it. The 2 TC's im looking at are:

1st.
Protorque unit, P/N PTC-11700C5LS, 10.5" 4L60E Low Stall between 2400-2600. Has 15k miles on it For $200 Shipped

2nd.
YANK PRO Thruster 4000 stall with a 2.4 str. Has 7K miles on it $450 shipped


So what would you guys think is the best way for me? I dont want a daily driver that is a pain to drive.

Thanx for your input

I would never buy a used TC...unless the seller is your best friend. Also ,in your situation and gearing, I would go with a stall around 3200-3500. This is just one mans opinion.

I was reading about the Yank Pro Thruster 4000 stall. It says that It has the driveablity of a 2800 stall. Does anyone have any experiance?

Default Hi-stall

I run 3:42swith a yank 3500 and I do not see a noticable difference in drivability even in heavy traffic. Have never driven a 4000 tho so can't comment on it.

I hate to sound stupid, but why would one need a torque convertor? And what does a "stall about 3500"?

Default convertor

Don't know if you are just being funny or not but an automatic tranny can't function without a torque convertor. It is the fluid coupling that takes the place of a clutch in a stick shift tranny. The numbers designation is the RPMs it locks up at. Modified cars use hi-stall convertors to stay closer to the power band of that particular engine.

It depends on what your future plans for the car is. If you plan on putting heads/cam (good size cam) in, then I'd go with the 4000 stall. If you plan on putting a blower or any sort of FI on the car, then you'd probably be better with the smaller stall.

I have a Yank SY 3500/3.42 combo in mine and I like it. It doesn't feel as streetable as a converter with the higher STR, but itworks for me.

The higher the STR, the less you'll feel the slippage, especially with a gear in it. The best way for me to describe mine is that it feels like a clutch car when it's being let out smoothly...........until you brake it up and then the tires light up like a Christmas tree!

I would stay away from the pro-torque.

I would not go for either of these T/Cs. The PT4000 is more of a race T/C and not the best choice for a DD. I had the Pro Torque 2400 in my car. It is a good little T/C. But does not improve your cars performance from a roll. Also as mentioned above installing a used T/C in your car can be risky. Unless you know the car the converter came out of, it would be wise to have the T/C rebuilt before installing it. IMO you would be better off with a T/C like the Yank SS3200 with your 3.42 gears.

Even with 3.15 gears, this is true. The Yank SS3200 is a great converter for a daily driver. Very tight and great performance plus it's more eficient than the stock converter.

yank sy3500 and 3.42's and my car screams!

drives great! you will need a good tuner to tweak the shift points (upshift and down) along with the firmness.

Is there a difference between a Pro 3400 and Yank 3400? What if I took the ProTorque for $200 and then just had it restalled? Let say to 3400? They will do it for about $200 I think. For a Restalled 3400 TC for $400 isnt bad is it?

Thanx

I don't believe Pro Torque makes a 3400 stall T/C. Yank makes a 3400 stall but it is for FI applications. If I were you I would get the Yank SS3200. It is a 9.5 inch T/C which would be more efficient and lighter than any 10.5 Pro Torque T/C.

If you are looking for the best bang for your buck, I would look at a Fuddle Converter. I had a Super Yank 3500 TC and it was too loose for my driving needs. I purchased a Fuddle Performance 3000 converter with a 2.0 STR ($400) and its much tighter. Both converters at the track got me an 11.7@117 time.

The Protorque is a great little converter that will do wonders for your car, in my opinion. Also Protorque, Inc. is a great company to do business with. They will re-build & re-Stall your converter for a nominal fee. You best bank for the buck would be the Protorque. if you are building a race car then maybe I would think otherwise. I had the 2400 and 3.42's on my '98 and it was a fantastic combo. Go for it.
