I am still having weird torque converter lock/unlocking issues. And was just wondering if the computer was controlling it.

 

Yes kind of, no wires are going to the converter, you control fluid flow to the converter through solenoids. Who wrote your programming and have you talked to them with your concerns?

 

Hypertech out of the box programmer. But it does it with out the programmer.

 

I would be VERY VERY cautious regarding programmers with the TorqShift transmission. Many of the "generic" programmers are known to cause transmission issues due to the fact that they do not truly reprogram the transmission. I'm not a tuner guy so many this unit is OK, however I'd make darn sure this is the case otherwise you'll find out how expensive TorqShift repairs can be.

 

Talked to Hypertech. They said they do not touch the torque converter. All they do is increase line pressure to firm up the shifts to allow for the increase power going to through it.

FWIW

 

Personally, I would trust some of the guys on this forum who are very knowledgeable about tuners over HyperTech. HyperTech (as with any other company) may or may not tell you all of the pros and cons of their product. The tuner may not have anything to do with the torque converter issues you are experiencing, however it may lead to even more costly problems down the road. IMO unless you really do the research and know the ins and outs of adding a tuner to a 6.0 PSD you should stay stock. Just my $0.02.

 

Thank you for your opinion.

 

Did I see that these tranny's learn how you drive? And shift accordingly.

Look at post #7 for doing the re-learn on it. Lots of good info on this link.

 

Wow, now thats a ton of info. Did he like design the darn thing?

 

I think he is a 6.0 cyborg. LOL.

 

Must be, is his last name Ford by chance?

 

Yes, the computer controls the torque converter 100%. It commands it to lock and to unlock.

Yes, you saw that, but no, they do NOT learn how you drive. They learn how long each shift takes from when the computer commands the shift until the shift has completed. It then adjusts the pressures to make each shift complete in the time programmed into the computer.

 

Could it be telling it to lock/unlock at 2250 RPM's? Or shoudl it just lock at X-rpm and stay locked?

 

It locks by a table of vehicle speed vs. pedal position. There are also several things that modify the speed, so it is really hard to give a hard and fast number of where it locks and unlocks. It will also slip (by design) during a shift.
