Converter Stall Speed

[gpse3400]

I was wondering if anyone knew the stall speed of the converter from a '94 Grand Am 3100 4T60E

crappy, I belive its 1800 like the montes

[Rhedalert]

1800?!?!?! I thought Chevy at least would get the same as like the Olds or pontiac w-bodies. My car's 2600

[Manitcor]

nope, Ill be stealing mine out of a olds for the rebuild, someone told me theres a 2800 available in something, Ill have to ask that person again what it was though

1800 doesn't suprise me at all. Although I'm not sure, I was told that mine was like 1898 or something like that...I don't know why they wouldn't just say its a 1900 though if it is.

btw that 2800 stall comes from a '90 Cutlass, I have a hookup that can get them for about $100 if anyone wants one.

[gpse3400]

Is that from a '90 quad4 or from a 3.1? And if it is from a 3.1 is that specification the same for '89 2.8/3.1?

[Manitcor]

not sure, Ill have to check, Ill let you know

Im betting its the quad4 becasue that thing revved so high

Quad or not...they should adapt to the 4t60(e). The TCLock up meterial is different though.

YOu can take advantage of a stalled converter with gears. No sence in runing 2500 stall on a 3.05 gear on a heavy car. The theory of stalled converter is to get as close to the engines peak tq. for better takeoffs. Pass the engines tq with a over stalled converter and performance will suffer alot. High stall with low gears(3.05) and on a heavy car and it will feel "jerky" or harsh. Not to mention the torque converter will heat up the trans oil faster. Just a caution.

Yep, im well aware of that, I want a 2800 stall converter to complement my t65 build which will include 3.69 gearing. With a 3400 that should put me right where I want to be power wise at the launch. The trick will be learning how todo it with out braking the tires loose like mad. I still need alot of pratice launching

[ProjectMM]

what about the 4t40 or the 4t45, in the newer N bodys? I've got the 3.29 factory gear ratio. would that stall be to high?
