    2-3 shift flare

    I think this was the kit. https://www.sonnax.com/parts/3052-zip-kit I did it like 8 years ago. I installed it myself. If you go this route, make sure you keep track of the solenoid locations. Because you can mix them up. Some will fit in multiple locations. There's actually serial numbers on the...

    2-3 shift flare

    When i put the Sonax rebuild kit in my valvebody, I didn't replace the solenoids. When the lockup converter started acting up, I talked to my friend at a local transmission shop that I had bought parts off for years. He said the real problem is having steel valves in an aluminum valvebody. They...

    2-3 shift flare

    I had the same problem with a 4-5 shift flare. Turned out to be the valvebody in the trans. I installed a sonax rebuild kit. It worked for about a year then I started having problems with the lockup convertor not holding. When I got the new valvebody it looked a lot different. Once installed I...

    Transmission running hot in sand

    Yeah, I have a gen 1. My thinking is cooler fluid is better than hot no matter if you're towing or just regular driving.

    Transmission running hot in sand

    I put in one of these thermal bypass valves, https://pbhperformance.com/product/6r80-thermal-bypass-valve/ and the larger factory cooler. In town driving my trans temp rarely gets above 160 and towing a trailer never gets above 200.

    Any transmission guru's in here??

    When I replaced the valvebody in my trans, it came with a calibration tag. After I installed it, I sent it to the dealer on a rollback to upload the new calibration data for solenoids in the valvebody. I was told don't even try to drive it before programming it. I put the stock tune back on it...

    slight jerking/shaking at idle

    I would change the upstream O2 sensors(the ones before the catalytic converters). Especially if they are the originals. As they age their response times slow down. This would be more noticable at idle. I change them in my vehicles at 100k miles

    GEN 1 RPMs stick at 1500 when coasting at low speeds.

    I have a 2013 with a 5star tune. it does it with the 5star tune, doesn't do it with the stock tune. I have both tunes saved with hp tuners, I was going to compare files when I had time, maybe data log the fuel trims when it happens. But if @MFNG is seeing it stock. I wont even bother. I'm used...

    A/C not cooling properly

    Did you try to empty the system and put a vacum pump on it? That will get out any moisture in the system. Then fill it with the proper amount of freon. If it has too much freon it wont get really cold.

    Thermostat going bad?

    Sounds like there is air in the coolant system. Try putting the truck up on ramps or parking it facing up hill. Take the radiator cap off and run it until the top radiator hose gets hot. Make sure you have the heater on high so it runs through the heater core. That should get any air out.

    Clunking sound in front end at low speeds when turning steering wheel

    I had a similar problem. I would only feel the clunking when pulling into a parking lot or driveway that had a little bit of a lip higher than the road surface. I changed just about everything in the front end. Including the rack and pinion. Turned out it was the dust shield where the steering...

    GEN 1 2014 Power Steering Whine ideas?

    I put the full lee power steering kit on mine. It has a slight whine. But I don't break power steering pumps anymore. I have had good results with Lucas in the past. The Lee unit uses their own fluid, I didn't want to add any additives to that.
