info about s42-ZF reverse
A while ago I asked about strange feelings when going into reverse, with my'90 F-350,7.3 5spd O.D.,bought used
Well I have found out something that might be good for others to know. The ZF 5spd uses a syncronized REVERSE, first one I've ever heard of.
So If anyone normally lets a little grind go on entering reverse,make sure it is not allowed anymore. Because syncro's do not stand much grinding. I'm now replacing the reverse gear and other parts of the rev.syncro, plan to have $300.00 in parts alone.Luckly a friend (pro truck mechanic) and are doing the labor. Just thought the group should know this.

i have the the same reverse. i roll the truck ahead a little bit before putting it into reverse. either put it in first or start the truck in reverse, theses are ways to avoid grinding, good luck to all

I noticed on my soon-to-be '94 F-350 with a 5spd manual(I don't think it had an overdrive) that the reverse gear also grinded a little. Any chance you might now what type of transmission it probbably has? I bet that it probbably also has a syncronized reverse which is going out. The truck only has 180,000 miles on it, but it still looks great and runs wonderful.

The only way to really know what you have on there is to get under it and look at the id tag on the side of the tranny. usually mounted on left side. thats all i can help you with, good luck

I'm not sure, but suspect that the only 5spd is the ZF pronounced ZED_F, until very recently. Now I think there is a 6 spd.
If the trans. has an aluminum case it is most likely the ZF
There is a plate, very easy to see, on the drivers side.
Mine started by occasionally jumping out of reverse while starting to back, then jumping out while backing, then I couldn't hold the shift lever in at all.
In the other 4spd's reverse is a standard gear that actually changes position. in sync'd trans. the main gears are in constant mesh,and only small cogs change position , so if a grind occurs there is no where near the amount of metal to stand the wear.
I replaced the reverse gear and the syncro parts involved, a total cost of $380.00 and expect the labor to cost $150.00 that's because the mechanic I passed wrenches for is a friend who gives me a break Best of luck PHIL

I forgot to mention that only after starting the pick-up the reverse gear grinded a little, and barely would stay in reverse. But, after driving the pick-up a little ways, there was no problem. I do think that everything on the pick-up is probbably heavy duty, it was used for towing I think a large trailer. (weight/length/whatever unkonown) Either way, when I do end up takeing over the pick-up (probbably in 2-3weeks) I have plans to put it in a Ford shop for a little while, the engine doesn't start very well, and while it is in there for that purpose, I might as well have the transmission looked at(whatever trans. it may be)
