Picked up 2015 Yukon

[the 18th letter]

2015 with 97k on it. Good service records, but based on driving and trans temps, no transmission thermostat change happened so I expect no other precautionary measures were taken . Does anyone have the part and service bulletin numbers handy? Plan to change to a Denali grill and 20 inch rims. Hope she serves me as well as my 99 has and my 2009 did. Pardon my photo skills, I'll get better lol

Looks to be in excellent condition and very well maintained. Love the color. Glad you have service records.

My transmission in my 5.3 2016 Tahoe went out at 123K miles. The GMC dealer replaced it in Florida and of coarse the thermostat.

Had the transmission fluid changed out every 40K miles at Sheehan GMC in South Florida and at Paramus Chevrolet before it went out. I will be due again towards the end of the year so will let Paramus Chevrolet do it as I should be back in the area at that time.

This is TSB for thermostat but says for 2016 up.

Thinking of using Paramus for the next scheduled maintenance. Did you change the thermostat on the trans prior to replacement at all?

My favorite color!!!!! Nice find for sure. Dig it.....


I did the the cooler thermostat upgrade. Better than the updated OEM ones. Towing I run 170 deg. in 100 deg ambient, and not towing 150.... Every little bit helps.... I think the quicker you can get the temps down the longer the life will be.

No. That was my bad.

Been dealing with Jim Kobernick at Paramus Chevrolet. He managed to take care of me late on a Saturday a few weeks ago with a issue with the cooling fans. He even got me a super cheap rental Equinox out of his fleet for the weekend. If you talk to him mention you know Gary with the White Tahoe. He will probably take better care of you.

Thanks and ordered. A reliable transmission shop should be able to install this with no trouble, or better to have the dealer do it at my scheduled maintenance when manual says transmission fluid should be changed?

Yeah, any good shop can do it for sure. May be worth having the fluid and filter changed and do this at the same time.

What's the difference between this and TVB 86774933, besides price? I see they are only slightly more costly, but it is a GM part. Apologies if this is a stupid question.

No stress, the TVB is a complete replacement of the bypass thermostat. It is the updated design that has a lower temperature thermostat in it. Supposed to be 180 degree if I am right. The other one keeps the factory housing and only replaces internal components inside the valve. All the truck guys swear by it and Im sold on it after installing it.
