The price of the Ford RDU fluid at the dealer is ridiculous. I thought the ULV was bad til I bought the RDU fluid...

Agreed. I cleaned it up all with brake cleaner and I will run it around for a couple days. I could also add dye if needed.

During the last few oil changes, I noticed a slight drip running off the lowest point of the PTU. A bit difficult to trace, but quite sure it's not coming from the axle output seal. Had a closer look yesterday, looks like maybe it is the sensor in the bottom of the PTU. Not sure if that is a speed or temp sensor, but I did have a similar sensor fail and puke pressurized trans fluid last year. It was part of the auto stop/start system. Anyone have experience with PTU leaks?

Welcome!

Ok thanks guys. Found similar info on the B.I.T.O.G. site. I will stick with the ULV.

Any transmission guys here know if there is any advantage to switching from ULV to LV trans fluid? My understanding is that the super thin ULV is part of the effort to reduce parasitic drivetrain losses to boost fuel economy. Not necessarily the best for wear or longevity. I'm thinking of switching unless there is a smart transmission guy that knows otherwise.

Have you had the most recent transmission software installed? Sometimes that helps. Personally, I would do drain and fill only. There are other things that can cause shifting issues, so a good diagnostic might also be useful. The ecm relies on a number of engine and drivetrain sensors to determine shift points, harshness etc.

HA! It sure is a fun machine. I still have a bit of runway yet, so by the time I check out, it may have an aluminum 6.0 LS, coil overs and whatever other goodies I can dream up.

I hear ya. Well, your post has me convinced that it as something to do with EGR too. Maybe even MAP or TPS. It is definitely some sensor contributing to engine management at low part throttle. I dont know much about newer systems, but I was doing my apprenticeship when GM started with efi, and EGR only came into play once the engine was at operating temp and in closed loop. I like the vehicle too. Mine is over 160,000 kms now and no torque convertor issues. At this point, if it goes, I will replace the whole trans myself rather than lose money trading it in for something with similar problems. I'm done throwing money at Ford Credit. My kids will get this car in my will!

Good call on the hose clamp. I did the full procedure heating up to operating temp and using the level plug. A dealership did the last drain and fill and I didn't entirely trust how they did the fill.

So far so good. If it does come back, it could be a weak battery issue.

Thanks very much Omar! I will try it today and update later.

I have not used Forscan yet, but one thing I've found with mine is that the "tugging" only occurs on a damp, cool day, on a cold start. Once everything is up to operating temp, the condition quits. It was far worse before replacing the dpfe. I have not tried to replace the egr itself yet, but I may do that next.

My 2019 Titanium has 2 distinctly different seatbelt alarms. One is a gentle, tolerable chime that does the job. The other is a sharper, more urgent ding that is less tolerable. I've tried to figure out if there are specific triggers, but it just seems to be random as to which alarm I will get. Thanks for any insight.

Nice to see people doing these kinds of mods and upgrades to new vehicles.
