I have a Tank TT2600 stall currently in my truck and am considering going to a Yank Pro Truck 3000. My question is this: Would going to a higher stall equal to more strain on the transmission? With the stroker I have going in and a Radix strapped to it, I'm concerned about long term wear and tear on the tranny. I've already had my 4L65 built, just curious what I'm looking to do to my tranny.

 

i asked the same thing about going from my built up 2500 from my stock converter. he told me that i would feel a great difference with a yank over mine. i would think it would strain it a little but not more than your right foot. i suppose it is all fluid flow and as long as the clutches are locked in good it will build more fluid presssure. how much for the 2600

 

Its going to depent on the str ratio of the converter and how much torque you are delivering at the flywheel. Having a converter that stalls higher and has a higher torque multiplication will increase the strain on your trans.

I'd be willing to bet that your little TT2600 would stall well over 3K with the torque of a stroker and blower pushing it. Not sure about the pro3K, but I'd bet it would stall even higher.

 

Yes .. it will be more strain. You will be on edge with added cubes and boost anyways though.

 

The only added stress would be from the Stall Torque Ratio associated w/ the PT3000. It's not going to be a whole lot more stress, some but I wouldn't worry about it...I'd be more worried from the cubes of the stroker...

Does the PT line have anti-balloon plates? I'd seriously look into a converter with them if they don't already do. Basically all that input torque causes the converter to swell under load...not good.

 

As it was/is, it was stalling right at 3k.

 

Stall = input torque + vehicle weight.

With that PT3000 and the blower w/ stroker, dont' be suprised if you flash stall to 3700-4200rpms...

 

If I remember correctly, parish8 said his TT3000 would flash to 4000+ when he would hit it with boost / nitrous off the line. I'm sure boost / stroker and a TT2600 would stall mid 3000s off the line.

 

TT3000 is ~11" and 2.25STR right? That PT is about 10" from what I recall and has a higher STR doesn't it? So if it's smaller in diameter it's gonna be looser too. Hrmmm.

BenKey... you may want to get one that's stalled lower initially. PI can stall them from 2400-4000rpm+. I'd get one that's like a 2600rpm stall (their STRs are 2.55) and a multiclutch. It'll be close to $1K new or you could get a used one from this site for about $400, have it restalled for free (as long as it's still under their provision), and for $300 more have it converted into a multiclutch setup...be like new for ~$700 only.

A flash stall of 3800rpms seems mighty high to me, I could live with it but you may not want to, that's why I brought up a lower stall PI. All their performance ones are 9.5" made of steel, 2.55STR, balloon plates, etc. etc. They are excellent converters and what I'd use...
