Dear folks,

I´m in the process of interchanging parts between a 1975 F150 (360 v8 + T18 4 speed) and a 1978 F350 (400 v8 + NP435 4 speed).

Is it possible to interchange shifters between the T18 and the NP435?


Thanks a lot!!

 

No, they are completely different.

 

Thanks a lot!!

 

No X2, so the smart guys say:
NP435 = aluminum top cover w/8 bolts
T-18 = cast iron top cover w/6 bolts Warranty Plate TRANS code: A = NP435 (N-1965 only) / F = Warner T-18 /
P = F350 Warner T-19.
Warner shift lever retainer cap (8MTH-7220) threads on/off.
NP435 shift lever retainer cap (B8T-7220-D) has two notches, is retained to shift tower by two pins.
To remove this cap, it must be pressed down and held down while turning it counter clock wise to remove it. (Its spring loaded and twists into place, we removed one and it was a 2 person job. Put the trans into 2nd, 4th, or reverse, then one person holds the cap and applies pressure, twisting in a counter clockwise direction. The other person hits it from the top with a hammer to get the cap to go in below the two clips that hold it in.) People unaware use pliers or channel locks to remove it, which tears out the pins.
Originally NP435: Reverse-down towards the seat while Warner T-18: Reverse-up towards the dash.
The reverse shift pattern was changed circa 1973, but I can't recall for which of these 4 speeds. ( I believe it the NP435)
Note: There's another 4 speed: RUG SR-OD Single Rail 4 Speed Overdrive introduced in 1978 F100/150 300/302, TRANS code B

 

Nice response Rich!
