Thank you for the informative video, sir. How does one test for power and ground at the TCM - are there particular pins? The 1-through-80-pin connector I am working with is similar to the one in the video. Thank you for any guidance you can offer. It means a lot.
Hey there, yes there are pins to test at the connector for power, ground, ignition power and datalink. There should be information available for the connector mapping if googled 👍
Thank you so much for the incredibly prompt guidance, sir. I greatly appreciate it. As directed, I found a map for the connector and checked the pins. It appears a small cracked developed in a pin, causing it to loosen. After addressing this matter, the truck ran properly. Thank you for taking time to support and direct me. It was pivotal.
Thanks for the informational video,one does this transmission has a tft sensor or does the turbine speed sensor in a way sends in a way a a reading to the TCM on internal temperature of the tranny . Thanks in advance and god bless you?
I would first check your battery connections and fuses. Then test the power and ground at the TCM connector. If you have strong power, ground and good datalink and it still doesn't connect, you then have a bad TCM
I have a 2009 pet 335 with transmission problems, the computer showed low voltage and for which the solenoids failed, the mechanic said that it is an electrical problem, I have been looking for something wrong with the wiring for days without luck, any ideas?
Firstly check your battery voltage and cables for loose connections. If its good, you need to test for power and ground at the TCM if you're getting low main power codes. Verify you do have low voltage and then follow the harness back checking rub points, etc. You can do a wiggle test on the harness while your meter is plugged into the power and ground circuits to help pinpoint the location of the corrosion.
@@AcousticHills yes that's what the scanner showed! but my mechanic has time until Saturday and the dealership in two weeks, and since the speed sensors are not expensive I wanted to change them to see if that helps
Apart from programming basic features, you cant do much without the OEM software and a certification for programming from Allison, you'll be blocked out without it. You should just bring your TCM into a shop that is Allison certified with a programming station. There is a calibration sticker on the back of the TCM that tells them what CAL is in the TCM. If the TCM is dead, order a new one already programmed.

Does the turbine speed sensor require any flashing/programming following it's replacement?
Nope

Hey there. Yes this has a temp sensor inside the trans.
My scanner doesn't connect with the transmisión and every currente from the tcm is low, do You think the tcm is burn?

@@AcousticHills I did it, I just removed the sensor turbine and it was stuck in corrosion, it came out in pieces
@@ignaciohb4372 ok good. I thought you meant the computer (TCM) had low voltage
@@AcousticHills yes that's what the scanner showed! but my mechanic has time until Saturday and the dealership in two weeks, and since the speed sensors are not expensive I wanted to change them to see if that helps
@@AcousticHills My truck fails whenever I pass a hole or in some sudden movement, apparently it is getting stuck in some gear and it is a high gear
Good evening, my dear friend. Can you make a video of how to program Alison's mind?
