Auto Trans Solenoid Regulator Valves! So important! 

Well heck! You’re just an hour away. You should come up and visit sometime! Thanks for the kind words!

Usually when you get a new TCM, you'll need to program it. But since you are getting it from Ebay, maybe the seller has the ability to program it for you. Regarding your shifting issues, I'd check to see if the line pressure is within spec. It sounds like line pressure high for some reason, and a solenoid or TCM could cause this. Good luck!

Sorry Yura! I don't sell these, I only teach them, lol! Regarding the TCM, I'm not sure what happens to them. It's just one of those last things you replace if you know the solenoids are good, the valve body is good, the clutch endplays are good, and the trans air checks good. There's nothing else left! Lol!

It might be the solenoid pack. When you have it apart, you might air check the clutches and inspect the valve body as well.

@@siuautomotive thanks

I don’t know anything about that trans, but the video applies to everything that uses a solenoid regulator valve

I’ll have to do the calculations, but I’m almost positive that they leave the sol reg pressure the same. On some of their older performance kits, they have options for increasing pressure, but in units like the 6t70, they are just fixing a worn out valve body.

@@siuautomotive thanks for the response, and your videos are awesome! I just assumed that they always bumped the pressure up, but I guess it may depend on the transmission model and what its known to have issues with or known to need improvements with. I have a 6R80 with weird shifting behavior and Transgo has a shift kit with specific things being addressed for it. "Common concerns with this transmission are TCC shudder, rough coast down shifts, gear ratio error and solenoid performance codes. Firstly, these complaints are the result of the wear in the pressure regulator (PR) valve bore and the pressure regulator valve balance bushing. Secondly, the torque converter clutch regulator valve design and calibration were in dire need of an upgrade to address the TCC shudder complaint." Would there be benefit in upping the pressure for the converter to keep it locked up better? Provided the lock up clutch is not warped or cracked? Is the 6R80 converter clutch the same as the 6L80? With same problems?

Transgo makes a great product and I think it'd be worth putting in a kit to see if it addresses the complaints. I do know that the 6R80 is known for solenoid issues, from either contamination or solenoid seat wear, and this would also cause your issues. I don't think increasing the pressure would help your issue, because these transmissions are always monitoring shift speeds and the computer would likely try to work to reduce the pressure, negating any modification you did. And, by doing that, you could end up making the computer work outside its limits of adaption. The 6R80 uses a different design of torque converter than most. It's still a two-path, but it uses a captive clutch on some designs. I believe they are having issues with converter lining flaking and their plastic stator falling apart. If you pull the pan and you find friction material or plastic, it's probably from the converter. It's a difficult converter for the TC reman shops to rebuild because if its design.

@@siuautomotive Thanks for that info. Sounds like the 6R80 has its own issues. I just bought this one and trans oil was black at 80,000. Had a lot of fine metal on the magnet. Seems way to black for fluid thats supposed to last for 120,000 miles. Trans might not have much life left. I changed fluid and filter for now. Going to put the transgo shift kit in next hoping it will extend its life until I'm ready to rebuild it.

And of course i'd replace the Converter probably with an upgraded one.

I know ….. the US is like the only country to hold on to the imperial system. Sorry about that, lol!
