Transmission frustrations

[1952b-3F152]

All right, I give up. I have been on the internet looking for a freaking model number to the numerous transmissions that were in a 1952 dodge 1 1/5 ton truck. I have looked at the transmission page of the shop manual online. All they say is "new process 5-speed or 4 speed" but no model numbers. Can anyone tell me what the 4 speed sychro trans is. And while I am asking how about the rear end as well. It is a 1 1/2 ton truck with a single speed rear axle. Thanks Jon:confused:

My 3 1/2 ton has a missing transmission as well. All I can find out is 5 speed direct or overdrive? Sure hope someone has more information on the big pilothouse transmissions.

Try the guys over at the American Truck Hysterical Society forum, they are a very knowledgeable bunch on any old truck.

They came up with a part number for the brake master cylinder for the 46 Fargo and the guy at the Navistar dealer was shocked to find it in stock at his warehouse...expensive, but in stock, new.

ps...if you're into old trucks, the daily "What am I?" is alot of fun and somedays extremely interesting:

Geeze, and I belong to ATHS too and never even thought about their forum? Talk about wasting resources.

Thanks for reminding me PatS!

I have a five speed (non syncro) out of a 42 1.5 ton. I saved the driveline and scapped the truck since the body was beyond shot. I'm located in SE NY if your interested pm me. You also may want to post the question on the Antiquetruckclubofamerica.org website. Mike

George,

Your truck would have had a New Process 5 speed most likely W/O overdrive-all 2-3/4, 3, and 3-1/2 ton Dodge trucks 1948 to 1953 use the same H-duty NP 5 speed. 2-3/4 trucks have a smaller U-joint yoke at the rear trans brake drum. I`ll post a picture of what your transmission should look like later in the week.

The 1948-53 1-1/2 ton Dodge "F" series trucks usually came with a New Process 420 series spur gear 4 speed or whats called straight cut gear 4 speed identified by the drain plug that is angled at 30 degrees. The other NP 420 4 speed available was a syncromesh model identified by the drain plug that comes stright out the back of the trans. Both these transmissions are the same as the pick ups but have a larger 10 spline input shaft and different parking brake drum with a larger driveline yoke attached. 5 speeds in this 1-1/2 tonner would be probably a special order only. An OverDrive 5 speed is EXTREMELY rare to find in any of the old Dodges!

George, here are pictures of a New Process 5 speed out of a 1951 2-3/4 ton dodge truck. This is the same trans as what should be in your truck except the rear brake drum/ u-joint yoke is different.

Jon,

I can help you figure this out using cross reference manuals and parts list I have however I need to know the exact model number of the truck....B-3-F, B-3-G, etc. Also woudl be helpful if you could obtain the T# of the engine and your serial number of vehicle. I know.....they didn't make it easy did they?

Bob, thanks for the pics. Now I have a little more to go on. I was surprised to find the top off the trans with shifter under the seat? The pictures will give me a little more to go on. The guy I got the truck from said he'd help find one but needed more info first.

Here is a picture of the bell housing the 5 speed trans came off.

Bob,

I have a picture of mine looking under the cab, I'll compare these. It does have the big drive shafts and u-joints. Just a thought after I do find a trans (you wouldn't happen to know of one for sale?) I have a 3 speed brownie with an under, direct and over that should fit between the transfer case and transmission. Would this be ann advisable addition to pick up a little extra speed?

Thanks george

I don't think you'll have enough power for the twin screws and the brownie. I don't think Dodge even offered the 5 speed OD as an option for the tandem trucks. The tandems sucked up a lot of power and speed capabilities. I will look at my stash of tranny's and if I have one I'll let you know George. I parted some of these big trucks out in the 80's and can't be sure of what is left. I do have a similar trans but it's out of a 1955 hemi 3 tonner-same trans but different longer input shaft and e- brake assembly.I think the bolt patterns the same /trans is partially taken apart. Don't know if it could be modified to work. These Dodge big trucks are a rare breed!!

Ya, I didn't think of the power issue? I guess 105 or whatever horsepower isn't a whole lot with the kind of weight even the empty truck has. I've been looking around here and have the word out but the biggest Dodge truck I've found is 1 ton or less. There's still hope for finding something locally but may have to advertise nationally to finally find something. If you have the chance to check stock I'd certainly be interested in purchasing one. I haven't been to you neck of the woods in a while but it would definitely worth a road trip.

Thanks - george
