Was torque converter slippage to help with tranny problems?
I just took delivery of my '06 and absolutely love the truck so far.
Although I'm fine with the way the tranny is stock, I would much rather have it with less slippage.
My question is why is it designed this way?
Did Dodge do this as an easy way to stop some of the tranny problems they were having?
If one was to upgrade or replace the tranny with more lockup would there be a negative effect on other areas of the drivetrain such as driveshaft, rear end, etc. etc.?
I don't recall driving or hearing of a similar setup with slippage like this.
TIA

Good question.The HIGH stall speed that D.C. uses has been around since 1989.some use to say it was on the cheap(used same convertor in the gas and diesel)but I bet it was or is due to the torque and Rpm's that the Cummin puts out at certain rpm's etc.Or it good be because of production cost but since the towing warslast several years)of the big three I doudt it.Be nice to ask this to a engineer in the know.

I don't think there is any problem with the torque converter. The torque curve of the engine is nearly flat from 1600 rpm to 2500 rpm. It's a different story if you're going to bomb the engine.
I don't like the computer programing. It is much too speed sensitive and not load sensitive like GM and Ford.

The stock TC is crap for TQ multiplication and stall for a very good reason. The 48RE is rated at 530 ft/lbs of input TQ. The stock ISBe puts out a bit more than that at very low rpm's.
Defuel and slip to save the $$$ in warranty work or, heaven forbid, the cosst of building the thing right from the start.
