Does anyone have an idea for a fix for this? Are all T-18 top plates the same?
The shift pattern has reverse to the left and up.
I have looked for a replacement top plate but cant find one that has the same marking.
The truck is a 1972 but the owner said the motor (352) and trans are out of an old truck but didn't have much info besides that.
I know the top covers are different on the '79 and later and that's due to reverse changing to over to right and back toward seat. I think there were two different versions on '78 and earlier though.
Reverse on a T18 is to the right/up. 1st gear is left/up. I dont know if there is a fix for the above pic. That is where the pin from the shifter sits in. I guess if you can weld cast iron, it could be filled in so the pin cant move around.

Up to 1978 model year, reverse is right/up. '79 and later T18 have reverse right/down and the top covers are different. I learned this when I discovered what I thought was an NP435 in my '79 was actually a T18. I assumed it was an NP435 due to how it shifted, then decoded the door tag when I got it home and learned something new.
I found out my 72 f250 4x4 had a T18 in it when I was trying to find reverse right/down like the np435 that was supposed to be in it. Then I punched the dash when I found it right/up.

I thought mine had been swapped when the door tag indicated T18 but it didn't shift like any I had ever seen. Crawled underneath to inspect closer and sure enough it was a T18. I have since rebuilt it and it is definitely a T18. In '79 there were a few changes made. The reverse shift lever was removed from the case and moved to the top cover. All shift forks on the top cover and the front bearing retainer were changed to aluminum. The case and top cover are different than earlier models, but all the internal gears and shafts are the same as far as I know.

So is this not a T18 then because reverse is to the left and up. What would it be?
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 presseddownand helddownwhile 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 taps 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
The one man board trick to get the NP-435 shift lever retaining cap off.
Maybe a little to new for a 67-72, but I can not imagine much changed.
Looking closer at the top cover where the vent is located is throwing me for a loop. All the top covers for T18s that I can find have the vent located where I have the arrow pointing to the left. Yours appears to be in the middle...
The bosses on the side here don't match a T18 either. I am beginning to wonder if you have a T19. They didn't offer those in Ford trucks, at least light duty trucks, until the 80s though. I am trying to find out if they were ever offered in older Ford trucks. You mentioned it doesn't have the original engine and might have a 352. I am curious if a 352 or perhaps an FT engine from a medium duty truck was swapped in? Back to the interwebs for more sleuthing. I like a good mystery...
