I have an np 210 5speed does any one any information on them ? ratios?, shift patterns? O.D? direct drive? casting numbers on the side are c-90101. information on the interwebs says its a clark but there is a NP gear logo casted into the side, and it is a crash box, there are no synchros. Any info on these old boxes would help.

 

1948/56 Ford truck parts catalogs lists no New Process 5 speeds, only Clark 5 speeds (5 Speed Direct and 5 Speed Overdrive).

 

see the np logo? I forgot to mention that this trans came out of a 65 ford 4x4

 

Then it's the New Process 435 4 speed that was introduced in 1965 F100/350.

Installed in 1965/79 F100/250 2WD and 4WD & 1965/72 F350.

 

Thanks Number, but this is no np435, after 2 hours on the interwebs of researching this trans I found out its a np 210.

 

If the trans is from a 1965/66 F100 or F250 4WD or an F350, it has to be the New Process 435, because it was the only 4 speed available in these trucks.

No F100/350 was available with a 5 speed. 1966 was the first year the F500 was available w/the New Process model FL-1 5 speed.

 

I thought I'd post that I just pulled a transmission with those same numbers C-90101 and NP markings from behind a 1954 F600. It was bolted up to a 256 Y-block. I believe it is what the Ford manual calls their 5-spd Medium Duty Direct transmission. Unfortunately I was hoping for a 5-spd OD, to get a bit more speed out of my old rig.

 

Hello did you ever find the information you were looking for? I am also curious to get some more information about this transmission. Mine came out of my 1955 Ford C-600. It was attached to the stock 235 Y block. I would like to find some seals to clean it up and get it running. I spoke to Matt Weller Truck in Wyoming, Mi. He had a parts catalog and part numbers, but can’t get the parts.

 

Interesting tranny! Have you tried putting it in the highest gear and calculated the ratio of input shaft to output shaft? If > 1:1 its an overdrive transmission which are super rare. I've always wondered if the 5 spd OD from a larger truck would work in a smaller truck.

Just so you know, this is an old thread dating back to 2019. So JERUSSEL may not answer you
But others may.

 

THIS LOOKS LIKE A CLARK/FULLER 5 SPEED OD LIKE A 251VO OR A 280VOHD TO ME
