tranny shifting out

[gordon23]

This discussion recalls a problem I had this past summer. F53 Ford chassis and 460 engine.

We're in the hills in Vermont and I'm shifting into
3rd gear to hold it back and save the brakes. Becomes steeper and I go down to 2nd and the tranny holds for a couple of minutes and then shifts out of gear. I lean on the brakes and shift back to neutral and then back into 3rd & 2nd. This time it holds for a couple more minutes and lets go.

The routine continued later in the day after stopping and shuting the engine off. Seem O.K. in 3rd but going down to 2nd it does not like.

Can the shift vs. r.p.m. be tweeked by a mechanic
so I can depend on engine braking next summer on high incline decents.

I hate winter......I hate winter....I hate winter

I had one vehicle (Nissan PU)and the automatic transmission had zero resistance for deceleration. It worked fine but when I coasted it was like I put it in neutral. Nissan still wanted over $2500 to fix it and that was over 10 yrs. ago.
Everybody downshifts , including me when on hills, to save their brakes but this also heats up your automatic transmission just like when you're going uphill.
Hope yours is just a minor problem, good luck.
BTW, I bet Driver is wondering if you have a Ford on the Workhorse forum.
