I have attempted to look for similar posts but non of which were exactly like mine.

I was on the Highway driving and my truck went from D to a roll with no sound. I just heard the RPMs Rev-ing up, I pulled over put it in Reverse and back into drive and i was fine again. This occasionally happens, so I have to dive in A4WD to avoid from a rolling stop. But as long as I drive it in R for 5-10 feet, its fine for a while.

There are no sounds, no check engine lights, no issues with shifting (knock on wood) and fluids are topped off, it has 148,000 on it.

Could it be TCCM? I don't want to spend the $200+ if its not going to fix the problem.

i have an envoy 2003 with a 6-cylinder engine and 4l60E trasmission, i rebuilt the transmission 4 months ago, after 2 months i had a problem with the generator(alternator) so i was obliged to jump the car for few times, after i repaired the generator, the car was in limph mode and the shift A solenoid was damaged. i repaired it. 1 month later the transmission pump was broken, i repaired it also. and now i have a delay during the shifts from 2nd to 3rd and a little of slipping, i replaced the solenoids after 15 minutes the solenoids are damaged again, and the problem has returned. someone has told me i need a new transmission. can anyone help me with this problem? is it an electrical problem? or it's the transmission? how i can solve it? it's been 4 months i have problem with this transmission.

      Towing In Loose Gravel

      First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move.

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.
