I have 2018 Suburban with 6L80 Trans and 5.3L engine. I am chasing a high temperature problem for the transmission. I am wondering if all such suburbans have passages in the radiator to cool the transmission fluid. I was trying to get a temperature reading with a infrared temp gun off of the trans lines into the radiator and could not find the the trans lines into the radiator. I know that on some 2018 suburbans there are trans lines into the left side of the radiator, but I can't find such lines on my Suburban. So what I am looking for is definitive confirmation that some suburbans do not have transmission fluid lines into the radiator.
I thought that about "vintage" edition Broncos. Put some $40 steel rims on a Bronco call it a vintage edition and you can charge 28 times the actual cost.
2024 Sierra 3500 AT4. I run 70psi front, 80psi rear on larger 295/65R20. I tow 1-2 times a week 9klbs/1k tongue. it's a little rough empty, but I like having way more capacity than required and a little better mpg. got tired of airing up and down multiple times a week, so I just leave them there now.
