Every transmission I've opened has had the ultra fine mettalic slime on the magnet. Some of the filter clog and debris was probably from the clogged coolers. I flushed them the best I could forward and backwards when I replaced the transmission thermostat, but there's likely still some crud in...

Greetings! I've been gone a long while, but thought I'd come back with an update on the truck from this thread: https://www.bobistheoilguy.com/forums/threads/4r70w-transmission-overheating-failed-cooler-bypass-valve.302831 Vehicle history is in first post of that thread, with the addition of a...

Started getting a strange, intermittent "burning smell" when at stoplights, but by the time I got to destination and opened hood, it would dissipate and I couldn't locate source. Didn't smell like smoking oil, and instead smelled almost like diesel exhaust. No obvious leaks besides the residue...

Parents' house has a Regency unit since early 2000s. Very cozy radiant heat and will heat whole house on fairly cold days with the blower going. Milivolt system so will work even during power outage, which we made use of many times. It runs a lot during the colder months, sometimes at much as 10...

Repair successful! Removed old thermostat and used two stubs of flex hose to bypass it, then drained and filled pan with fresh fluid. Unhooked return line at cooler and started engine to flush out cooler circuit. Plenty of flow through coolers and pushed a few more quarts of fresh ATF into...

Originally Posted by Trav Does this one use an external thermostat/bypass? I did one some years ago (it may have been an 4R100 not sure of the year) that had one that was failing, more fluid was bypassing the cooler and going directly back to the transmission instead of through the cooler. Yes...

Torque converter is holding at cruise as far as I can tell. It stays locked under mild acceleration and there is a definite unlock feeling under moderate acceleration where the revs jump up. Letting off the gas will have the revs drop back down and then a slight bump as it locks again. I'll...

No codes stored. By the time I had scanner available the overheating had stopped. Subsequent driving hasn't had the OD light flash again, but also haven't been long enough to get it super hot again. There was significant flow through the coolers when I had the hoses disconnected. Maybe try...

Originally Posted by CT8 172,000 miles gets into the trans being worn. There is always room to find a reputable trans pro to get an other diagnosis. Except this trans is the rebuilt unit with only about 70k on it. If it was dying and slipping and roasting fluid, I'd expect the coolers to be...

Vehicle history: 2005 F150 XLT 2WD with a 4.6 and 4R70W. 172k miles. Has both radiator end tank ATF cooler and small aux cooler piped in series. Boss bought it used with ~40k miles; original transmission gave up around 100k miles and got replaced with rebuilt unit. Truck had some other issues...

Changed oil a few days ago and did not add any oil to filter before installing besides a few drops on the gasket. Again filled with Valvoline 10w-30 Synthetic with Maxlife Technology and used a Mann W917 filter. Similar ambient temperatures. Similar vehicle angle. Compare to the first video...

I suspect the BPV could be failing to open when you let off the throttle. BPV relies on vacuum/pressure differential between charge pipe and manifold. Valve stays shut with a small differential while throttle is open; large differential when throttle is closed causes valve to bypass. Get a hand...
