- 1994 Ford Ranger
I've swapped transmissions in the past with no difficulty. I have a 1994 Ranger that is sickly - I bought the truck from an acquaintance and he said he was having to top off the fluid (ATF) about once a week and putting 300 miles/week on it and that 4th had stopped working.
I pulled the transmission out of the truck - the first thing I noticed was the inputshaft bearings (or in this case, lack of). The bearing casing was disentegrated. The bearing cylinders were still in there, but this was 'why' it was whining and wasting fluid. I figure new bearings and new seals should take care of that (with a thorough cleaning).
The other issue though is that 4th gear didn't work and doesn't seem to work while I've got it down and working on it. I pulled the cover and tested each of the gears and all work and engage properly except 4. When I put it in 4th gear it shifts (or I can shift the shift bearing by hand when the cover is off) but it won't engage.
Looking into the body of the transmission, there don't appear to be any destroyed teeth and the synchronizers look fine. I just don't understand HOW it is supposed to work to know what is broken.
Can anyone explain how 4th gear engages and why it might not work on my transmission?
(For TL;DR - looks good inside transmission housing, but 4th gear doesn't engage even though it shifts into the 4th gear position - what should i look for?)
Thanks so much

(I'll post pictures if needed - just let me know what you want to see - i also got a schematic from southwestgear.com for the M5R1, so feel free to use that numbering and I can check out any part)
