Torque Converter
 

Just installed a new converter. Went to stall the converter and went to 3000 then to 5500. I've never seen one do that. Converter guys please help.

Re: Torque Converter
 

Are you doing a static "stall test", where you hold the brakes, mat the accelerator pedal, see how high the tach goes, and then release the accelerator pedal?

Re: Torque Converter
 

No on the transbrake.

Re: Torque Converter
 

Just as bad.

If you cannot fully release the car with your foot on the throttle, never do that, ever.

It drives the stored energy right back into the sprag and the stator.

That said, your problem could be anything, from a converter problem to a mismatch, to an ignition problem.

Mark,

Tell me what you need i'll try to answer as much as I can.

Re: Torque Converter
 

What is the combination ? What stall speed were you expecting ?

Re: Torque Converter
 

SS3011,

406 and powerglide about 6400rpm.

Re: Torque Converter
 

7", 8" 9"...optional sprag, mechanical diode? Manufacturer ?
Did it on first try after install? Still doing it?
What does it drive like now?
Like Russ said.. What was it supposed to stall at ? According to who?

Re: Torque Converter

8' with a sprag JW
yes it went to 3000 then 5500 all 3 times I tried

6400 from JW

Re: Torque Converter
 

No

Re: Torque Converter
 

6400 sounds high for a 406 bracket motor,,or what are you trying to run with the car?

What was the old converter acting like right before you took it out?

What does JW say about this?

Re: Torque Converter
 

JW Built the old converter about 5 years ago for a 355 stalled @5900 with the new 406 6400. I believe its driving though the converter now...but will print et slips!!! Called them and wanted to make the car more efficient without affecting the consistency.

Just put in in last night so i have not had a chance to speak with JW.

What would recomend for the combo?

Ck carb, either too rich and taking time to burn up the fuel or too lean and a lag before it gets enough.
