    8hp70 heater bypass

    Thank you, sir! So far it is fun to drive with that 10speed trans. The 5.3L v8 has some pep. Wish I went with the 6.2L but with gas the way it is now, I settled for the 5.3. Love the group here, definitely will miss yawl.

    8hp70 heater bypass

    Just an FY! I have finally resolved my issue with the over heating transmission. Traded in my 2016 RAM 1500 for a 2023 Chevy Silverado Z71 Trail Boss LT with the 5.3 ten speed trans. I really did want to but the fact that the dealership was not willing to look at the problem without charging me...

    8hp70 heater bypass

    well then I'm waiting for it to throw a code like last time and then do that. Cause they won't do the job right away. First they have to order the transmission which takes forever. So when they say its ready I'll bring it over with everything put back in place.

    8hp70 heater bypass

    I have a question. If and when I bring my truck to the dealer to replace my transmission under warranty, (which I think is going to happen) do you guys think I will need to undo CAULK's Heater By Pass and put my AGS panels back in place? The reason I say this now is because the truck is...

    8hp70 heater bypass

    Funny, I didn't mention the other day that after I removed all my AGS shutters (except for the tops and bottoms) I ran over to the automated car wash. So I wonder if my AC Cooler got cleaned? I'll have to look at that this week when I replace my PCV valve. Haven't done that yet and I am at...

    Yeah, I would say it is running cooler so far, but as far as testing the trans, I haven't done a long highway test yet

    Dealer cost on replacing spark plugs?

    So did anyone re-use their coil boots or order new ones? And if you ordered new ones, which ones. I am looking in RockAuto and there a few different brands including the NGK. I am due to do this job soon. I am at 99K miles on my 2016.

    8hp70 heater bypass

    I have gone and removed the AGS, all but the top and bottom. I did a short run around town for 30 min. But that's not really a test. The highest my trans temp got was 154* which has always been normal to me. The oil Temp got to 215* and coolant was around 205* off and on. I won't really know if...

    8 speed transmission issues

    Yes it is. The only thing I am towing is me, myself & I. Some times the wife too.

    8hp70 heater bypass

    Oh Ok, thanks. That's probably it. It was kind of random, just sitting there. I'll check that when I'm working on it again tonight.

    after deleting your transmission T-STAT, are you still able to monitor your transmission temps?

    8 speed transmission issues

    You know that is the one thing that I haven't replaced, and that is the TMU. I have the same story as you. Had my transmission go at 61K miles (now I am at 99K) and then I noticed after driving a long trip from North GA to Central FLA I got a warning from the truck that the trans was...

    8hp70 heater bypass

    OK so I started taking the shroud off preparing to do my investigation with the radiator to see if anything is plugging it up. I noticed a plug that is not connected to anything and was wonder if anyone knew what this goes too.

    8hp70 heater bypass

    Well did this test and the electric fan kicked on, like it should. Guess I can scratch that off the list. Still need to pull a part the front grill and see if there is anything clogging up the area. Ran out of time this weekend.

    8hp70 heater bypass

    Other than my heat issue, I love my truck. I do feel that caulk04 by pass has worked (have had it installed for almost a couple of years now) because I have not experienced the 285* temps any more. Like I said it is not all the time. I have driven for 2 hours on hot days and the temps have...

    8hp70 heater bypass

    I was doing some online searching again and I came across another forum where they were having the same complaint about overheating transmissions. The very last post which was from 2021 said he found a fix. This is his quote and I was wondering if this could be a possible fix for me: "I just...

    8hp70 heater bypass

    I still have my shutters in place. And I will do an investigation and pull the grill this weekend. If this was something consistent I would think that it would be some kind of blockage. But that it happens from time to time is weird.

    3-way valve?

    8hp70 heater bypass

    Well I guess I am revisiting my one and only issue with my truck and that is the heat issue with the transmission. For the most part the truck drives great, but occasionally after driving around for a few hours when slowing down there might be some slipping and then the occasional coming to a...

    Operating Temperature

    for some reason when I got the 190* TSTAT someone said from one of the other discussions on this site that I could get away with this TSTAT w/o getting tuned. Am I wrong?

    Operating Temperature

    Ok, who or where would I get that done at? And if I don't get that done will it be terrible if I didn't get my ecu unlocked and then tuned after replacing the TSTAT?

    Operating Temperature

    If I replace the stock TSTAT with a 190. How do Reset the electric fan controls to go along with the lower temps? I have already replaced the coolant at around 70K miles, I'm at 98K now.

    Operating Temperature

    Really!! I was told I would have to pull the bed out to get to the gas tank in order to replace it. Not that I am doubting you but how does it get away from having a fuel filter?

    Operating Temperature

    Thanks for the input. I may do the removal of some of the active shutters and replace my TSAT in the near future. My truck is coming up on the 100K mileage (98K at the time of writing this), so I know a lot of maintenance has to be done by then anyway. I still have my original break pads with...
