Transmission Fluid Change Reaction

[DT444T]

Wait you guys don't just buy a whole new 10r80 every 60,001 miles? Jk, well actually I'd like to see some high mileage transmissions here that haven't needed work.

I plan on having mine done at 50k and I'm a very light driver.

Bone stock PB trans with right at 60,000 miles and it's towed back and forth across the country a couple times. I'd bet at least half of all the miles are towing or hauling something. If I don't need the truck I take the car. Shifts smooth and doesn't make noise.

I AM going to get a fluid change before I take my travel trailer 2200 miles (each way) on my next trip to California.

Given ford is making 20% of 2024 production PBs, their options are limited. They'll learn and adapt or go under.

No they won't. CAFE is moving trends as a whole, ford is just the first to iron out the bugs. Next up a new round of hybrid trucks from other companies. Only one not yet showing their hand is GM, and one thing you can bet that's coming with that is a hold-my-beer moment. All those praising the pushrod milker will have it all over their face. Think GM botched up their 'new' EV push, ya ain't seen nothin yet.

Folks have no idea what's going on, this explains it right here. This sharp sudden increase is changing everything. F150 sized trucks have to have a ~25% bump in efficiency going from 2021-25s else they're fined / have to pay someone like tesla for the offset. Literally funding rivals if they can't meet the fuel economy requirements. More hybrids and electrified platforms are coming.

A better chart by vehicle size and year

These numbers can be a little confusing as there's different standards here vs stickers. What it comes down to is the F150 needing ~26MPG sticker by 2025 else they're fined $$

What a long strange trip it.......is already being. ??

You might have been the first to jump in. (Prius?) Or you can be the last to. Free choice. And as it should be.

But it's an unstoppable force. Tomorrow isn't going to be less of these kinds of choices. It's going to be more.
Parallel Hybrid
Plug-in Hybrid
Range Extender Hybrid
BEV

Some flops, some hits (the Powerboost was and is a hit), and hopefully a grand slam or two.

Dealerships with legacy locked stances will have plenty of folks that are sympathetic to their complaints. But they can't stop the march either.

I'm just one consumer. Sitting in the cheap seats and refusing to wear the jersey of any team in the debate. But I'm convinced there's some really cool vehicles (and technology) coming. Not really hard to believe since there's already been some amazing examples.

I think folks can be too hard to impress at times. ??

Ford's been in the hybrid business since 2005 when they came out with the Escape Hybrid. Bought a 2006 then and it's still going and going. OEM Battery in it. I can tell its losing capacity. When new it would go about 2.5 miles on the battery (level road) where now it seems to only make about 1 mile. Still, so long as it can start the engine we'll keep it. That battery was a NiMH type battery and the transaxle using the HV battery started the engine. In the F-150 Powerboost the 12VDC battery starts the engine.

My 2023 5.0 with 3.31 has presented the same symptoms since day one with banging and clanking when downshifting coming to a stop, so now he advised me I need to check the fluid level. Once mine warms up shifts get smooth, which his dealer told him is due to the fluid expanding and normalizing pressures/operation.

My '23 5.0 w/ 3.73 does this as well. I've been wanting to check the level on mine but it sounds like such a huge hassle to do. Please update if you get your level checked because I'd be very interested to know.

Jumping in from a 3.5EB 10R80, in an expedition, but still Transmission Fluid related.
we have 115K miles on it, (bought it used with a 3rd party extended warranty) and i just took it in for the transmission fluid drain/filter replacement.
the trans fluid was black as dirty oil can be. AND it was 2 quarts low... it appears to never have been disturbed since it left the factory. The Transmission shop inspected it before pulling the pan down and there are zero signs of trans fluid leaks. The filter had no metal shavings in it when they looked into it. (lucky me...)

It seems that Ford has been under-filling 10R80s at the factory. so I would recommend do the Filter / fluid replacement.

Also, they have to bring the trans fluid temp to 205DegF to actually finish checking the fluid level so that it is not under-filled/over filled. and the fill location/micro dipstick hole, is right next to the catalytic convertor, so they will most likely get burned if they are not extra careful and wearing gloves...

Cheers.

Let’s hope a new administration can slow this down (CAFE) until technology catches up. I’m all for innovation, but it should be the consumers choice. Quit using my taxes to subsidize vehicles nobody wants.

The auto companies agreed to what the current standard ramp is. The standards are not difficult to hit, especially given that the tax credit has remained pretty much unchanged for PHEV vehicles. The $80k price point isn't difficult to hit and a $7500 tax credit would make them cheaper than their ICE only counterparts. The PB engine option has been ~$2k for approaching 4 years now on the F150 (though suddenly free for 24). Had they just taken it up a notch with a 15kWh+ batt and a more powerful electric motor we could have had the benefits all along (e-motor should be able to effectively brake and accelerate w/out need for ICE). The Lariat for instance w/ tax rebate would have been cheaper than an XLT ICE only truck.

This was really easy money / mileage upgrades to add, ford and other truck makers just didn't have the testicular fortitude to do it. Yes, a 550hp / 700tq powerboost would encroach the raptor and it's pricier R, but the demand for sub $80k versions would have created a waiting list. Instead they came out with a version that while still a good value proposition, doesn't have people queuing for it. They could have skipped the current implementation of e-motor / TC variant and instead locked it to 4wd choosing instead to use the transfer case / prop shaft area negating trans mods (if not running an electrified only 4wd system). The starter generator could be a 6kW unit for topping up the HVB if motion is limited, otherwise it could scavenge power from the drivetrain. Several ways to go about it, they just chose not to.

There's really no more meat left on the bone for making these things more efficient. No secret ace up the sleeve for ICE and the aerodynamic increases have little room left on the bone sans full air suspension able to hug the ground. As such the only logical option for increasing mileage at this point is electrification supplemented by the grid. Easy easy, especially for migration to heavier platforms. Work out the easier positions first ala F150, find the weak points, migrate to larger vehicles. Compound drive shafts make it easier for motor integration post trans allowing for 2WD variants. The head first leap into EVs ignoring ICE/hybrid systems makes no sense. All it took was looking at raw materials and grid demand. It didn't require a $10bil to figure this out.

Copper alone took 4 decades to double production and we need to quadruple it? Grid capacity has scaled about 1% per annum but needs to double for full electrification? A company with over $150bil/yr revenue was some how caught off guard by basic facts involving key components of their business model? CEO has got to go.

Certainly does not hurt to replace. I’m considering the same service but would want full pan drop and filter replacement. We don’t drop the oil plug and refill while leaving the dirty filter. I see no difference in servicing the trans. Although fluids have no doubt improved over the years that is to meet the increased demands and stresses placed on these very complex components.

I don't tow or haul anything at all ever...I am crazy wanting to drop the pan and rep[lace the filter at 50k miles. Currently its a 2022 STX 4x4 with just 10k miles on it....so 50k will be in about 3 years or so

 

[Ronin1973]

Does type of daily service change anyones mind on this? I'm not arguing either way, I am just curious. For instance, let's say you have someone who never hauls or tows and drives their truck on the hwy 100 miles a day and that's it. Truck sees city driving only briefly to fuel up once a week. Would you consider that "light" enough to wait and change the transmission fluid at 150,000 miles?

 

[HammaMan]

150k miles is a long time for an oil. Here's a little spreadsheet of estimated additive pack life. Not sure what happened to make ULV so cheap, but it's really a no brainer to use these types of service intervals at $6/qt pricing.

These are the current offerings of ULV -- of course there's also amsoil for ~3x the price
