Some trucks didn’t have a cold start rattle but could exhibit a knock noise at hot idle; the calibration corrects that issue. Which is the reason the reprogramming should have been done first. Not really. The general public spends far too much time and effort speculating about things via the...

Wow that’s ridiculous, a guy with a big ego who thinks he knows more than the engineers :rolleyes:

It really depends what’s causing the hard shifts. 6R is a clutch to clutch unit, meaning timing between one clutch releasing and the other applying is absolutely critical for transmission longevity. If one is releasing late or another is applying early, it will cause damage. The other aspect to...

Why won’t they install the new calibration per the TSB?

The first version of 21B10 came out in early Spring 2021. They paused the program to investigate the reports of shudder, which turned out to be scored cam journals due to poor maintenance/low oil level. 21B10 Version 2 was released in July of 2021; at that point they incorporated the ability...

F36 powers the active grille shutters, A/C compressor control valve, oil pressure solenoid, turbo bypass valve, electric water pump, transmission coolant valve, and vacuum solenoid valve. You’ll want to check the harness between the Battery Junction Box and those components for chafing, damage, etc.

If you’ve been running it hard it can consume excessive oil on DFSO events, which occurs when downshifting. The PCM update corrects that issue by limiting manifold vacuum on throttle tip out. Hopefully you didn’t run it hard with only 3 quarts of oil in it; oil level is something that should...

One hour of labor.

Long block, customer pay. Those vehicles had cam journal damage from poor maintenance/running it low on oil.

Sounds like someone installed the lights/harness too close to the PCM or its harness. That can induce electromagnetic interference which skews sensor readings, especially those on VREF.

B00A0:68 is just an indication in the RCM that DTCs are stored in the OCSM. So resolving the OCSM DTCs should clear that DTC. DTC B0061:64 in the OCSM when the passenger seatbelt is unbuckled and the OCSM measures voltage on the Belt Tension Sensor (BTS) signal circuit greater than a...

You’ll need to have the damage repaired and pay the dealer to recalibrate it.

Not likely. The program expired in 2022; owners were provided one full year to get it done. It’s a customer pay update now.

You may have a fuel system related issue. Misfire under load is typically ignition related, but with all components being replaced with OEM the next most likely possibility is fuel pressure dropping under load. I’d start by checking Fuse 27 in the Battery Junction Box under the hood. The fuse...

He’s trying to save you from yourself. Those quick splices damage the circuit, cause voltage drop, and induce corrosion. Taping it to or sealing it does nothing to change the fact that the wire has been cut. You’ll end to spending $3000+ on harness replacement later in the trucks life all for a...

Yes, the sooner the better.

That’s literally the entire point. Without the new calibration the phasers will wear abnormally and eventually fail, regardless of what part number is installed.

You’re not analyzing a part from a YouTube video, especially from an “engineering” perspective :facepalm: I don’t know how many times I need to reiterate this before people stop coming up with their own “theories” that don’t align with the facts. Especially when your video claims they’ll “put...

The old parts haven’t been available since 2019. So almost impossible that they used “old parts”, but that speculation continues to run rampant on social media of course. Program 21B10 is a PCM calibration update; it’s entirely responsible for the operation of the engine and VCT system. The...

Rod bearings would be a good check, along with cam journals. When the top end is starved of oil the cam journals will be scored up. However, I think @Old-Raptor-guy summed it up well. There’s just too many possibilities for unseen internal damage to be able to make a definitive call as to...

Yep. It applies to all 2017-2020 Gen 2 3.5 built before 11/30/2019.

Curious what they find in the oil filter. These engines used low friction coated bearings, which may have saved it from spinning a bearing when oil pressure was lost.

If you didn’t have recall/CSP 21B10 done back in 2021 you will continue to face repeat VCT failures due to wear. Without the new calibration the phasers are starved for oil at hot idle and begin to wear abnormally, resulting in failure.

Well the first red flag is both turbos “going bad”. That’s does not just happen for no reason, especially both sides. Did you retrieve DTCs and do and diagnosis or did you just throw turbos at it? There is no reprogramming necessary for the wastegates. Did you replace the turbocharger oil...

As @smurfslayer said the 10,000 miles internal is the MAXIMUM allowable interval under PERFECT operating conditions. In other words, it applies to basically nobody. Full synthetic oil is recommended. Ford’s minimum requirement is semi-Synthetic. When certain DTCs set the PCM will disable boost...
