'95 Bronco with the 5.0L V8, 4WD
Driving slowly makes normal shift. If a little aggressive on the gas, the
1 - 2 shift is very harsh. All other gears are okay.
This Bronco is running oversize tires with the stock 3.55 gears. The hard
shifts started after the tires were installed, however this happened outside
of San Diego, and the problem started near Dallas. Overdrive is mostly not
useable with the current tires and gearing, but there was no other trouble
driving to Dallas. OD had to be switched off to keep the torque curve inside
of the speed range, this is cured with smaller tires or lower gears -- 4.10s
should do the trick.
The 1-2 shift was fine when the truck went to Dalas, now it is problematic.
My guess is a solenoid. I only know enough to be dangerous.
What say you?
