Engine Braking

We live on a hill. I tried several things to descend the hill with engine braking. Tried using the shift buttons to put automatic in first gear. It would still upshift so I had to use the brakes down the hill. Next I tried using the manual first gear but same result.

Today after a year and a half of ownership I found the solution. Use the manual first gear and press the tow/haul button. Gearbox stays in first gear and provides engine braking.

I did not know that! It is good info.
Would you call this "hill descent mode" meaning abs and tsc are fully engaged when in that gear and in tow/haul mode? We have a ridge road getting to and from our camp that is a real challenge in the winter. The main hill is transitional being steepest at the bottom with a sweeping curve in the middle! Don't remember if you have the 4x4 conversion.

Do not know about ABS & TSC. I suspect they are still operational.

2 wheel drive conversion.

So even with your 2wd-ls it would engage the front abs w/o your foot on the brake pedal right? I remember qualifying my Quigley rep that all those systems will remain fully intact after the conversion (but my wait continues until early April).

On my Super Duty, tow/haul locks up the torque converter when coasting allowing more control, and it will also downshift through the gears as needed. I assume the transit will also do the same.

Try just using tow/haul down your hill and see if/how it might downshift for you on its own.

Procedure did not apply the brakes. What it did is keep the transmission in first gear.

I think I tried the tow/haul mode without being in manual M1 low gear. Selected low gear with the button on side of gearshift lever but it would upshift to second. I will double check that today.

Tow/haul does not apply brakes for you.
However, in drive when you take your foot off the gas you can usually tell the torque converter is locked up, giving the feel of a manual transmission left in gear rather than neutral.
When you brake, the transmission downshifts as speed decreases, much like the old school toe/heel on the clutch, brake, and gas pedals (I miss those fun days!).
This is how it behaves on my truck, I'm not blessed with tow/haul on our Transit.

I was sort of asking if the ABS sensors detect loss of traction/wheel slippage when descending if the traction control features of braking and engine throttle control would also kick in. The assumption would be that those features are always on but pressing the tow/haul button must influence the logic somehow. I know my wife's VW has a dash light that flickers when TCS engages in heavy snow I think the van has a similar light so time and testing will tell.

I was confused. Today tow/haul does not work in manual. Using tow haul with the shift button to select first gear will still upshift going down hill.
Just shifting to first gear in manual without tow/haul does keep the gearbox in first gear.
