UT - Thanks for that little trick suggestion. Having mentally recorded and utilized quite a few "tricks" during my many decades of screwing with mechanical items... I know that many tricks do work. Must say this is one I've not heard of.
So, I gotta ask... even though I know the trany is 100% full from recent fluid and filter change - you still recommend adding extra 1/2 quart?
Have you found this trick useful due to the extra fluid level enabling the trany pump to have better fluid-access from its pan when on steep grade?
I believe I see the logic in this!!

If it works, your dip stick may be marked wrong. I have seen it before.
If it's over filled, you will see bubbles on the dip stick when you check the level as it's running. Hard to see, so look carefully.

"Sweetie" has under 40K miles. All fluids/filters are recent. Drives like a champ. Circumstance I've noticed is backing up a really steep, twisty incline on our property. There's little to no room to increase reverse speed before heavy grade begins. If/when I do coerce the RV to gain some reverse speed the trany pretty well pulls it up the steep incline. If I don't get reverse speed up then at peak of the grade the RV simply stops, even with engine revving fairly high. I don't let this high rev with no movement last but for a second. Then, I go back down the short, steep incline. Reason I don't want to drive up frontwards is because there's no turn around room... and I'd be scared s-less to back down the grade [due to fact I've seen other "front engine" weighted heavy rigs get in trouble there. Oh and by the way, did I mention the two twists/turns, one at bottom and one at top.
My predicament is: I carved out a parking place at bottom of driveway by road [we live in rural area]. Unfortunately, it's tight quarters make it difficult to work on or clean the RV.
So, my question: Is it normal for a 4L80E trany to basically "stall out" in reverse when there is little to no reverse speed and a very heavy grade is encountered?
Any suggestion/info/knowledge appreciated. Currently I'm not trying to back up the steep grade again... even though with a try or two I have been able to get enough speed to make it. But, I do not want to stress the reverse mechanism too much inside the 4L80E trany.

We had that happen once when I was service manager. We found the parking brake was not releasing. The brake was weak. It would hold the motorhome from rolling, but the engine was powerful enough to make the motorhome move under full throttle.
There is a adjustment on the gearshift that controls the brake release. If it is out of adjustment, the brake will not release in reverse. It will release when you put it in drive, but not reverse.
To test for this, put the engine in reverse and listen for the pump to come on and release the brake.

Thanks, ga traveler - I'll look into that.
Although... I believe our park brake is fully releasing. Pretty sure it's cable only; has old school T handle for brake release wherein the pedal pops up from floor to full upward position with resounding [standard old school] bang noise as it hits top of its release position.

Crawl under and take a look at you park brake (on the back of the transmission) If you see a cable and what looks like a servo attached to it, you have a AAPB (Auto Applied Park Brake) that is powered by a spring. That spring is compressed by hydrualic pressure supplied by the PS pump.
I had a 1994 chassis P30 that had both the AAPB and a pedal like you describe. I could definatly hear the PB being released when I took it out of park. Sort of a groaning sound.
Definatly worth a look like GA Traveler said.

I had a Ford transmission that was hunting and it turned out to be the brake light switch needed adjustment It thought I was applying the brakes so it kept shifting down for no reason.

The transmission very well may be at its limit-the grade is so steep that the transmission has reached stall speed (around 2400rpm). Theres a point where the torque converter can only do so much. Reverse ratio isn't as deep as first gear.

Thanks, Bill
I'd be discussing this with my decades trusted [and utilized] old-school trany genius "Jim", leader man at Horgan's Transmission shop... however... debilitating illness has forced the shop closed. Hardship for Jim's family as well as for the community loosing access to a renowned privately owned trany shop. We all miss getting to stop by and kibitz with Jim. He's a great guy!

If the gauge is pegging when you ground it that means the sensor has gone bad.

Added Recliners
Before and after. Interesting project with chair casters
Also added a toad. Didn't have time to get a braking system for it so it will go on a dolly for this trip.

New chassis battery. 4D , 1660 cranking amps and 1775 CCA. Heavy and very snug fit same as previous 8D that was in there that gave up the ghost.
Previous chassis battery was at least pre 2015 vintage.
