well, my trans is gone again! shifts are crap. now its hanging in gear again. could it be in my superchip? burning it out?

 

Drive without the chip.
All though it sounds like you have other issues.
Bring it back. Remove the chip so they cannot pass the buck..

Bill

 

it was on stock when they built it friday, its back there now. i doubt a superchip would burn one out in 3 days. imma tell em to fix it right, in a timely manner or i'll find a lawyer. it wont even shift if you shift with the gear pole.

 

has to be internal if the thing wont shift with the lever out of low doesnt it?

The trans is 2-3 days old.
Just bring it back.
I would like to see the billing of parts used (breakdown).
Also info on the TC.

Bill

 

ya, i know. i'm just well, for lack of better terms pissed off! but, nothing a stick of dynomite wont fix! these idiots cant get their head out of their butt and fix it right. now that my rant is over, is there ANYTHING that can cause these trannies to be dropping like flies?

 

well, i just took it out for a drive and it done fine (dad was out in it when it messed up this afternoon) he said it wouldnt shift from first. he's right....but only sometimes. i drove it a few miles and it was fine, then it would mess up a while. then fine, then mess up. it revvvvs to shift point, then drops rpms, then revvvs to 3400, then drops to 2500 then revvvvvs, then shifts.

 

And these are the same people that said they put a stall converter in your tranny right? This is what I was trying to tell you before. YOu may be hanging at the stall and limiting the shift point and duration. Tell the guy to get the CORRECT tc for your truck. Your tranny guy doesnt know crap. He is an idiot, and your finding it out the hard way. Shame shame shame, you know you should have asked questions here first, you have been here long enough. What did he put the stall at? 1.5k?? 1.7k?? If its cloes to that, its your problem.

 

what is a good stall speed for these trucks?

 

An OEM TC with a stock PSD the stall is in the 1.95 to 2.28K rpm range.
This rpm is with a multiplier of 1.93:1
Stall will change from truck to truck do to the amount of power put to the TC.
Stall has all to do with your motor package (torque output with mods).

Your shift issues can be 1 of many things (electrical/mech).
It was just assembled and needs to be hands on tested.
Did they flush the cooling system for the trans? Its 1 of the biggest mistakes
made!!!

Bill

 

Madvan, I think you have some info twisted in that big brain of powerstokes...LOL

What is the untwisted stall spec of the TC? (stock PSD motor)

Bill

 

well,it should be done by noon tomorrow. it was in the accumulator valve body. it has at least one sluggy valve, that controls the gears i am having trouble with. \

TORQUE CONV- the torque is a DACCO designed specifically for the 7.3 PSD, with performance mods for tow. it is a triple disc, solid brazed flat back, low stall. he had mis spoken himself when he said high-stall.

 

Bill, Nothing about torque converters is more misunderstood than stall speed. Stall speed is directly related to the amount of torque your engine produces--the more torque, the higher the stall speed. For example, a converter with a 2,800 to 3,200 rpm rating might provide approximately 2,800 rpm of stall speed behind a mild small block V8, but about 5,000 rpm behind a big block making 800-plus ft.-lbs. of torque. If you don't know your engine's torque rating, you cannot establish the converter's stall speed.most converter manufacturers list stall speed ranges, those numbers are very, very general guidelines, true stall speed is impossible to measure due to vehicle variables. The time-honored method of testing a converter's stall speed--holding the brake and revving the engine while in gear, doesn't work, mainly because the tires will spin before you reach the converter's stall rpm. And as we all know, heat is the BIG enemy of your converter and transmission. Stepping up to a higher stall converter can impose higher loads and create more heat, so proper cooling is essential. This is why I thought that the high stall converter that 2 strokes guy said he put in was so stupid. Excess heat EVEN WITH A HUGE cooler is never good. Since our motors develop peak torque at a relatively low RPM, the stock torque converters used with Ford diesel engines have a stall speed of 2000 to 2500 rpm, well above the torque peak. I thought that they were in the 1500 range, and the after market triple disc lowered it down to about 900 or so. I was wrong about that, I admit. Hope this info clears some tranny info up for everyone. Most of it is common knowledge to guys on hear, and I am sure they were just waitin for me to put my foot in my mouth. This is about all I know on torque converters. Sorry.

 

anyone familiar with dacco?
