    Truck running hot.

    That’s another thing to check given the miles and years on the truck. If the pump is not working then the coolant temp would rise very quickly. That would be noticeable.

    Truck running hot.

    First thought is thermostat issue. 2nd is to check coolant and oil levels (do this first though). 3rd is shutters not opening. I haven’t seen oil pressure that low in a running hemi but would need more info. You didn’t provide info on driving conditions or what you have checked so thoughts...

    8HP75 Transmission Fluid Change

    Here's an excerpt from the April 2016 ZF 8HP Service Information bulletin (50130 EN): "Depending on the driving style, ZF recommends a transmission oil change every 80,000 to 120,000 km or after eight years at the latest." Equates to ~50k miles to 75k miles. This statement is removed in the...

    8HP75 Transmission Fluid Change

    OP: The title of the tread is "8HP75... " but you indicate a 2015 5.7L in your profile. Did you get an upgrade - either new tranny or new vehicle?

    8HP75 Transmission Fluid Change

    Given the minimal differences between the 8HP70 and 8HP75 - the 8HP70 recommendations are probably relevant. Now would be a good time to drain and fill the fluid. Not all is replaced. The 8HP70 process is provided below (thx to Wild One's new transmission) - see the attachment.

    All Repair Parts @ Employee Cost!

    The rear area of my 2017 Ram 1500 CC cabin is damp and it appears that I'm in need of 2 bodyside aperture exhauster's. Part number I've been finding online is 68323649AB.

    PacBrake remote filter install

    I had a similar 6 psi oil pressure drop when I installed the PacBrake relocation kit. I tried swapping the oil filter (used 2 Fram XG2's) with the same result. The 6 psi drop is at >1200 rpm. Idle oil pressure was within 1 psi. I'm going to a RP 20-820 on next oil change - I'll post if there...

    Unidentified part

    Looks like a vibration damper. I have something similar on both sides of the truck. They are a 2-pack per side and larger

    Only ticks (cold) when I put it in gear

    Updated post # 4 to correct engine oil temperature (previous temperature of 80 deg F was the transmission temperature).

    Only ticks (cold) when I put it in gear

    I tried MDS disable, priming the oil (flooded start method), cleaning the injectors, confirmed fluid levels, and revving the engine to 2,000 rpm before shutdown the night before. No joy on any of them. So of these were low probability causes but gives some piece of mind. I haven't removed the...

    Only ticks (cold) when I put it in gear

    Taspeace, I have the same issue - quiet on cold start; knocking in reverse or drive for less than a minute. Typically gets quiet around 100 to 120 deg F EOT (don't have EGT). Quiet on subsequent start ups (already warm conditions). I checked the exhaust manifold heat shields and they are...

    What’s your favorite flavor of cordless tools?

    Back in the day (as in way back) I bought a few Porter Cable tools, all are still in good shape and get the job done. Switched to Dewalt for the miter saw and kept going with the 20v XR cordless gear. I’ve had no issues with the equipment and they get the job done.

    8hp70 heater bypass

    Reporting in after gathering more data on truck operation. Installed a 190 t-stat (Stant 48799 with Motorad stamping) and removed the AGS (middle shutters only). Average temperatures: Engine coolant 194 +/- 3 deg F Transmission fluid 181 +/- 4 deg F Engine oil 206 +/- 4 deg...

    8hp70 heater bypass

    When starting a vehicle the AGS is in the open position. Pulling the fuse prior to starting keeps them in that position (no power to move). I am interested in the AGS operating points - conditions at which they change position. I have not found any definitive data on it. Here's a summary of...

    8hp70 heater bypass

    Dan, you are correct. In my case based on the evidence to date, a significant causal factor in the overheating is the excess transmission fluid. The only changes to the vehicle between the two graphs is mileage, 2 engine oil changes and checking the transmission fluid fill level (with the...

    8hp70 heater bypass

    Here's a follow up to post #420 / 421: In post 425 I stated that ~28 fl oz of excess transmission fluid was removed while following the transmission fluid check provided in this thread (key is the leveling of the tranny pan and pre-test setup). After conducting some test runs to ensure there...

    8hp70 heater bypass

    My next step was to test with the correct fill, test with the AGS open (pull the fuse), then add the modified TBV. Now my next step is to review this fill. Daniel - I showed the charts to the dealer and they barely glanced at it. I don't think the techs/mechs actually saw the data, only the...

    8hp70 heater bypass

    How about overfill? I check the tranny fill level using the instruction set (from the new transmission). Leveled the tranny pan rails using a torpedo level. I started the procedure with tranny at 73 F (step 5). The tranny was at 93 F at step 13 and 102 F when I shut down. About 3/4 qt of...

    8hp70 heater bypass

    I've had the tranny checked by the dealer twice. The response both times is that the tranny is good and the fluid looks good. Specific questions about the TMU and TBV were given a short answer of "They were OK". Edit: I am going to be installing caulk04's modified TBV in the next few days and...

    8hp70 heater bypass

    Follow on to post #374 hawsk99gt & Daniel Ortiz, first post I’ve seen that is similar to the operation of my Ram. I have a stock vehicle but I’m awaiting the arrival of caulk04’s modified thermal bypass valve (TBV). This is not an attempt to reopen all the good work already done to explain the...
