My credo
A properly suspensioned Ranger can be safely airborne for up to 4 seconds at a time! =:O
Truck just sat unused for 30 days in the hot So-Fla sun and rain. NO fluid leaks on ground.:D Low-use vehicle, not quite 34k mi. on odo.

Fired right up, shifted fine, no feeling of flat spots in tires, took her on a short high-speed run a few exits down I-95 to pick up a mere 60 lbs. of bulky goods and toss it in the bed. Used all 5 forward gears and reverse several times, no incident.

Stopping at several stores on the way back, the truck would ROLL BACKWARDS when left parked in reverse gear, clutch out (engaged), naturally. This is the flatlands, so we're talking pretty mild parking lot slopes... WTH?

My habit is to nose into the parking bump in 1st gear, clutch in, brake in, shift into reverse, key off, release clutch, release brake. (Except on very steep slopes, stopped setting parking brake as a habit in a colder clime, where tossed-up snow could freeze the brake cable).

Putting it in a forward gear seemed to cure the problem. Of course being thus spooked, I stopped being lazy and engaged the parking brake too.

It's basically acting like when the engine turns off, it pops out of reverse... will characterize further when un-jet-lagged... but is this ringing a bell for anyone?

Thanks in advance... z-z-z-z...
 
Perhaps it wasn't fully in gear?

Modify your procedure: My habit is to nose into the parking bump in 1st gear, clutch in, brake in, shift into reverse, slightly release clutch to verify it is in reversekey off, release clutch, release brake.
 
Yeah, I'm thinking... perhaps after 30 days of not driving at all, mixed in with a few days of driving several totally different auto-tranny vehicles (and stepping on the phantom clutch, LOL), I've just lost the "feel" for reverse...? Will investigate further in a couple hours...

On a related note, even at full stop, clutch in, going from 5th to reverse is--by DESIGN--*not* a straight shot like going from 3rd to 4th... what mechanism provides that extra "jog" you have to make to get into Reverse?
 
Yeah... I B retarded, lol. Think I'll just leave it in 1st from now on, and shift to neutral before starting, as you're supposed to... belt+suspenders...

Still trying to figure out what mechanism provides that protective "jog" when shifting into REVerse...?
 
It's to keep someone from shifting into "6th" gear when not paying attention... And good thing too, I've done it twice in as many months.
 
if it is kind of jumpy when it is rolling, it
is turning the engine over. my 4.0 does that,
but not my 2.8. more compression maybe.
