My 87 F150 automatic transmission tends to make a "hard" transition from gear to gear. Not always but often it slams hard into the next gear. Also when I hit the brakes at moderate speed it will slam hard on the down shift too. Is it a bad torque converter or what?
87 F150 transmission question

which transmission ?
AOD ? C-6 ?
thottle rod or cable jammed in the 'max throttle' position ?
or perhaps it came unhooked and the 'failsafe spring' inside the unit actually worked for a change
Your TV cable is too tight. It tells your transmission when to shift and how hard. It's adjustble, but if you get it too loose a few months of mushy shifts and slipping could wear out your transmission.
I just picked up an 87 F150 w/4.9L engine and Auto transmission last night.
I shifts exactly opposite of TDs. Can't even feel it shift hardly.
What transmission would be in my truck (with the inline-6) ??

there's a test port on the passenger's side near the back (actually, there's three of them, two closer together about 3 inches forward of the corner and one almost at the corner, you want the middle one)
that one is the 'throttle pressure' test port
you install a gauge, pull the throttle cable out (or block the lever) by
5/16 of an inch, and adjust for 33-35 pounds of pressure at the port, engine at idle, in OD
What kinda gauge ??

I use a 0-100 psi hydraulic pressure gauge (since I'm measuring oil pressure)
