What 4spd did they use in a 79 F150 that had reverse way over too the drivers side and up. This truck has really high gearing and the owner says it has OD. Just wandering about this transmission. Is it a the TOD or SROD? I thought these came out later. Just never seen a 79 with OD, and sorry forgot to write the tans code down but I will have all that when I pick the truck up monday.

vaguely rings a bell it possible that its just geared different in the final drive and its a 4spd without a compound low gear cause typically a 4sp manual isnt a overdrive transmission exept for slipomatics you would consider a 4 spd an od unit
Well the truck has a 3:50 rear gear and it almost lugs the 300 six if you shift into 4th at less than 60. This thing really feels like it has a higher gear than than the ZF 5spd I put in my 89 bronco and its rear was 3:55 and the funny thing is they have the exact same tires 235/75R15 Goodyear WH. I was pretty sure I had heard people talk about a clark 4spd w/OD you could get in these but mabey I'm wrong? Is the T98 an OD I thought its 4th was 1:1.

they were most similar to the toploader. it was called a RUG4 (or something) my dad has two of these that he ran in vans. not bad little trannies, but not quite the load bearers that the bigger trans are. just don't do like my dad, use the clutch to shift...
I had a 79 F 150 302 with the 3 sp + OD RUG transmission. It was a top loader very similar to the regular 3 speed manual. The shifter was bolted to the side of it. The floor board had the same shifter cutout and boot as a 4X4 transfer case shifter. The gap between 1st and 2nd was pretty excessive. I still have the transmission in my back yard. I believe that the overdrive was about 1: .85
So they did off an OD I thought it had to be. I am hopping this thing will get good milage just running to town and such, just curios as to the tranny I hadn't ever seen one before. I plan on doing all the heavy hauling with the F250 in my sig this little 2x4 F150 with the six was going to be my economy truck, for $600 I said what the heck. Yeah .85 sounds about right really high and that excessive gap was pretty noticeable.

The RUG TS-OD 4 speed single rail overdrive is a "weak sister" of a transmission originally designed for and installed in 1977 Granada's with the 200 I-6 and 302.
One speed shift, you can kiss the little darlin' good bye.
The transmission was first installed in F100/150's and E100/150's in 1978 behind either the 300 I-6, or the 302.
Parts are EXPENSIVE and getting hard to find.
btw: No Warner T-98's were used in these trucks, last year for the T-98 was 1965, but only used for a short time.
1965 and later: The Warner T-18 was used on F100/350's, some Warner T-19's were used on F350's. But...most of the 4 speeds were New Process 435's, reverse is back towards the seat.
No Clark 4 speed overdrive was ever factory installed in F100/350's.
My Dad bought a new 81 F100 with a 300 and that 4spd od.The truck had no power at all and you had to slip the clutch just to get it moving.He kept 14 months and traded it in on an 82 Chevy.
My 79 was a 302 4spd. OD orig.The trans. was OK for just daily driving but they won't take abuse.My dad bought the truck new and we replaced the trans twice but they did go about 80-90 thousand miles apiece.We ran an old toploader out of a Must. in it for a long time.I had to fab up the stock shifter so it would would work and we wouldn't have to cut out the floor.I just turned the 3-4 lever upside down and made the rod a little longer.We could've used it with out the mod but 3&4 would have been backward.Pull back for 3rd and push forward for 4th.I know that's a long story to say they had the trannys and my truck came with one.
So this tranny should work for me because I really never have seen a need to speed shift a 300 (drive something else if you are in a hurry) and the heaviest thing it will haul will be a load of grass clippings or mabey some wet leaves in the fall. Worst case what would it take to stick a T18/19 in it?
hey you got good thing with that set up i bet it gets good fuel economy even though its not a racing truck the inline six in there is pound for pound for torque better than a V-8 I have a 1966 f-600 nasty old dump truck with a 240 six when I first got it I thought to myself man I need a v8 but after using it for awhile I got used to how it worked and refer to it now as the little eng that could it can haul 10,000 pounds and go 55 mph on the flat of course I slow to a crawl comming up hills but it does it and what I had to do is run premium fuel in it to not have to shift to compound low to make it up steep grades
I really doubt it this one has mechanical linkage and all the newer 5spds will have hydraulic. Any 5spd swap I know of needs just about every thing. New crossmember, shorter drive shaft, and hydraulic clutch set up.

Easy? define Easy.
There are some aftermarket 5 speeds like the Tremec. Some late model F series trucks have a Mazda built (read a bit fragile) 5sp that commonly would be bolted to 4.9 (300) or 5.0 (302). There are some HD 5 speeds bolted to 460s made by ZF. Not sure about the late model 5.8L (351W). I test drove a 460 powered F series that had a 5 sp that would be better described as a 3 sp with a granny low and an OD. These newer trannies need to have a hydraulic clutch linkage adapted to older pedals. Expect to have to make a custom driveline and probably move the transmission crossmember. Throw enough money and custom fabrication at it and it can be done. How much gas money are you gonna save in the long run? Ultimately I chose to use an old T18 4sd with higher rear gears, and tall tires. If I really need help to get going I have a granny low. At 30 I can leave the truck in 3rd gear around 2K maybe 2.2K RPM, and at 4th, in 60 I'm just under 2K RPM.. 1800 I believe from memory. With a 390 2V, I'm getting about 12 -13 mpg. Better than I ever got with my old 302
