Very heavy duty 5-speed. I found one in an old truck that someone dumped by a riverbed a long time ago. The truck was a really old flat-bed 2-ton+ rated city delivery Dodge truck with an old 318 V8. They only made them in 2wd versions though and finding replacement parts for them is IMPOSSIBLE. I forget which gears are synchronized, but not all of them are. I had a whole bunch of literature on them but it was so long ago its long gone now. Ultimately, its probably not worth your time. You'll have to use a divorced t-case or custom-make an adapter and people aren't breaking SM420's or 465's, so the added weight and bulletproofness is probably wasted.

Guidolyons is rigth about it beign similar to a Clark ... in fact during my research I foudn that there are a few Clark models of tranmissions that most of the parts were interchangeable with. But, IIRC, the Clark version was the one with the 7.xx low gear and the 542 had a higher granny. Anyone who used those trannies back in the day in anything sought out the Clark versions and trashed the 542's. The Clarks were synchronized more, IIRC also.

I have one, it is the NP542GL model. It is direct in 5th, with 1st and R being unsynchronized. Mine came out of a 1984 Chevy C60 school bus chassis, originally behind a TD427. It has a 13" clutch. The bellhousing is SAE (forget what #), and has a steel adapter that mates it to a Chevy pattern. It has a bolt on ujoint flange, IIRC it takes a 1480 size joint. EDIT: forgot, mine has the 7.33 1st gear. I believe yours has slightly different ratios except for 5th, use google and you can find exactly what they are. I also think yours has a different suffix (not GL), but I'm not sure. Also, notice the shift tower isn't bolt on like that Clark, but it is aluminum like the smaller NP trannies.
I was going to run this with a divorced t-case, but now probably not going to go that route.

Here it is sitting on a Radio Flyer wagon for size reference:



Shift pattern (and most likely why you were told it was a 4 speed, just like how the newer SM465s were called 3 speeds because of the L):

with the shifter base housing like that there is serious short throw shifter potential.
Im not sure what the gap between the gears are yet all I know it has a 7:1 first and a direct 5th. if the rest are more close ratio I just might.... :smokin:

going on a 4bt/6bt? looks like one in the background...
naaa that pic was from the guy im getting it off of Saturday. I do have a 4bt but thats up in Washington state. Jim Maules is building me a Cadillac adapter for it and its getting stuffed into whats left of a scout. :smokin:

Talk about a useful post :flipoff2:

I also forgot to mention that it appears you can use the bellhousing on my 542 to adapt a Spicer 3053A tranny to a Chevy engine.
Hmmmm... I don't recall anywhere in his original post that he asked anything other than "Have we ever heard of one?" Sooooo, yep, I have heard of one. Heck I have even seen one.

Do any of you guys know how to tell if it is a overdrive model from the numbers on the case? I have not found any links that provide this info and it is hard to tell if the trans is still in the truck and the truck is dead.

Np 542

I just joined...and I realize thi is an old thread. But I put (driving it today!) one of those in a 1977 Jeep CJ5 , back in 1992-93. It came out of one of my Dad's Studebaker trucks. a rusted out 1964 1\2 ton! Kind of overkill for a 1\2 ton...OR a Jeep CJ
Apparently Studebaker had Clark 5-speeds in some of their trucks: 1\2 ton, up to 1 1\2 ton..the Clark has a 1:1 5th gear. My New Process has a 27% O.D. and about a 6.5 Granny 1st.
She has a Dana 300 adapted...and a modified Gremlin bell-housing:D....and a SHORT rear driveshaft
