Well, I don't have any calibrations unfortunately. When the Silverado/Sierra came out in 1999 GM advertised this as a "feature." The programming causes the transmission to stay in second gear (to...

Since I don't really know what I am doing yet I am taking it to a local tuner on Monday to have the KR fixed and get a complete dyno tune. :yay:

OK, I have added it to the requests section. Now when can I expect it to be added? :pray:

Doesn't look like this has been touched in a while so I thought I would bump it up.
If the spacebar works for starting and stopping recording can the same feature be added for pausing and resuming...

Is it possible to change the programming that causes the transmission to hold 2nd gear (4L60) or 3rd gear (6L80) until the engine warms up? I live in the country and I don't like pulling out of my...

I wondered about that but dismissed it because that amount of KR is present from around 2000 RPM up regardless of gear. The amount of KR has always seemed high to me but the knock is not audible even...

OK, I set the TCC to not lock-up at WOT in any gear and that seems to have fixed the converter line pressure from spiking. Unfortunately, that didn't fix the issue of the engine stumbling around in...

I personally don't know which it is for your car that is why I suggested making changes only to the MPH fields and testing before you changed any other parameters. According to the A4 Transmission...

Just guessing here but if you have a 26" tire with the 3.91 gears you are not going to reach your commanded shift MPH by 5500 RPM. If you have a 245/50R16 tire, and accounting for tire crush from...

Anyone?

I have read the stickies and still have a question about this.
My question is my TPS shows a maximum value of 84% though it usually shows 83% max and at idle I am seeing a minimum value of 20%...

Oh, and here is the tune I am using. It is the base tune that I received when I had the harness made. You will notice that the engine rpm stutters in the 5200 - 5500 rpm range on the first WOT run...

OK, today I was able to capture several transmission parameters so hopefully there is some data here that will indicate the issue.
The first scan named 01.25.2008.1 is a little over 7 minutes long. ...

I must be doing something wrong because I do not have those pre-defined. I only have Trans Fluid Temp, Trans Output Shaft RPM, Traction Control Desired Torque, and Traction Control Torque as...

Do I have to create these myself? I only have Trans Fluid Temp, Trans Output Shaft RPM, Traction Control Desired Torque, and Traction Control Torque values defined.

Thanks for the info. I will try it in the morning. I don't think it is TM because I had that disabled in the past and the shifts came on like getting rear-ended by a freight train so I reenabled...

It's been awhile since I have been able to focus any time on working on my truck.
I haven't been able to figure out how to select/creat the PID's you refer to. Can you tell me how to get these...

OK, next dumb question...
How do I select the items above to log? I have searched help and the newbie sections but haven't found the instructions to set up specific logging options.

No, not yet but I haven't had time to work on it recently. I am thinking of making a trip over to Speartech to see if they can figure the problem out since they made my harness.

I have a problem with what feels like slippage at WOT at about 4500 rpm in 1st, 2nd, and 3rd gears. It only happens at this rpm and only at WOT. I can't tell if it would do the same in 4th or not...

I think I remember reading somewhere that the shift light would only work with the 6 speed manual transmissions not the auto's.

Look for voltage on pin 4 of the transmission connector and pin 12 when the key is in the run position using pin 5 or other body ground to make sure the TCM is being powered up properly.
I can fully...

I was afraid it wouldn't be a simple fix. I have my original PCM to operate the fuel gauge and temperature gauge and an adapter harness to operate the oil gauge. I guess I am going to have to make...

Same question here. I ended up turning the TM back on because the shift is why to harsh. No tire spin with AWD but I worried how long the transmission could withstand those bazooka shifts.
