5 Or 6 Speed Tranny With P.t.o?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

junkyardjohn · 01-24-2005, 09:04 PM

HI GUYS.... I'VE GOT A TRANNY QUESTION FOR YA . I'VE GOT A 1969 1 TON TOWTRUCK, WITH A 350/SM465 COMBO. I'VE GOT A FRESH 396 TO DROP IN AS SOON AS THE WEATHER BREAKS, & I WOULD LIKE TO UPDATE THE TRANNY TOO, BUT I WOULD LIKE TO KEEP THE GRANNY GEAR AS IT COMES IN HANDY, & THE PTO CAPABUILITY IS A MUST FOR THE WINCH BUT WOUND OUT IN 4TH GEAR, IT FEELS LIKE YOU COULD SHIFT 1 OR 2 MORE TIMES. ANY SUGESTIONS ON WHAT TRUCK HAS THE KIND OF TRANNY I NEED.?

JOHN

JimKshortstep4x4 · 01-24-2005, 09:25 PM

John,

They are kind of pricey but a Gear Vendors overdrive unit is an option. It will take the power and abuse. (Not that you abuse your wrecker!)

Jim

junkyardjohn · 01-24-2005, 09:39 PM

JIM-- YEP.. A GEAR/VENDORS UNIT WOULD WORK PERFECT FOR ME. TROUBLE IS THEY ARE A LITTLE SPENDY FOR ME. (AROUND $2400) I'D LIKE TO FIND A USED 5 OR 6 SPEED THAT I COULD USE FOR UNDER $1000 OR EVEN A GOOD USED GEAR/VENDORS UNIT. ANYBODY???

JOHN

grayw0lf · 01-24-2005, 09:52 PM

junkyardjohn,

I would love to see a pic of your trans/PTO & how it all hooks together. I've always been curious to see what one actually looks like.

*bisquik65* · 01-24-2005, 09:57 PM

My 67 ton here has the new process 4 spd with a spicer aux tranny . high and low range behind it,the old twin stick. I can get you pics of that if you want tommorow.. It has the pto plate on either side of the trans or the aux trans has 1 too. Its a really cool setup.. 1st one i have even seen...Erick

Tx Firefighter · 01-24-2005, 10:22 PM

I have an NV4500 ( 5 speed ) in one truck and an NV5600 ( 6 speed ) in another truck. Both have the plates for PTO mounting.

You'd likely be happy with either of them if you find one you can buy for a fair price.

Rod · 01-25-2005, 12:27 AM

I dont think your current PTO's gear pattern will match up to the newer upgraded trannies...ask a dealer that installs such stuff. I'd bet not.

THANKS THOSE ARE THE ONES I'LL LOOK FOR.

ROD -- I JUST HAPPEN TO HAVE A NEWER PTO TRANSMISSION . A GOOD PAL GAVE IT TO ME. I NEVER THOUGHT ABOUT THE CUT OF THE GEARS THOUGH, YOU'RE PROBABLY RIGHT. I WAS JUST GOING TO SWAP IT OUT CAUSE IT WAS 35 YEARS NEWER & LOOKED ABOUT 75 LBS LIGHTER.

JOHN

Rod · 01-25-2005, 01:12 AM

There are a series of letters and number that mean something to certain pto people that know what there doing. Write en down and tell a PTO rebuild place they will know what the application is.

Code letters mean such things as stud pattern metric or standard, pto is self lubrication or needs to have fluid pumped to it, 2 way type, 1 way type, which direction the pto shaft faces, shaft high or low position, mechamism to activate the pto...it gets interesting if you get someone to supply you a few pages from an old book or new book.

frost89434 · 01-25-2005, 07:30 PM

John--- Don't worry about the pto. Whatever tranny you get I can get you a pto for. As long as it has the provision for one.

junkyardjohn · 01-25-2005, 08:08 PM

GREAT JIM.. IN THAT CASE I GUESS I HAVE NO EXCUSE AT ALL, BUT TO PUT A 5 OR 6 SPEED IN. WELL I JUST KEEP ADDING TO THE WORK TO BE DONE ON THAT OLD TOWTRUCK. A COMPLETE 85 DISC BRAKE FRONTEND , A BIG BLOCK & NOW A NEW TRANNY & A NEW PTO. NOW TO GO ON THE HUNT FOR A NV5600 OR EVEN A NV4500 , BUT I WOULD RATHER GET THE 6 SPEED. THANKS TONS..

JOHN

crazy longhorn · 01-25-2005, 08:24 PM

Overdrive dont come easy , if you are drivin a stick truck! IMO , that 4 spd you have is pretty d@mn tough.....spend the buck, & add the Vendors(pretty much bullet proof combo).....if you have to do her twice, it will cost you

just one

old mans point of veiw. best of luck, crazyL

Rod · 01-26-2005, 09:55 AM

I'd like to know what you eventually come up with also...wouldn't mind a 5 or 6 speed in my 72 tow truck either.

72gord · 01-26-2005, 10:28 AM

The 6 speed is great for towing, always keeping the motor in its peak rpm range, but if you don't tow alot, get a 5 speed. Granny gear and OD are about the same in both but with the 6 you have an extra gear. I have a 6 in my 2001 HD with an 8.1, works great on the trailer...alot of shifting when not. I would think it would be great on the wrecker though John, good luck in the hunt for one!

junkyardjohn · 01-26-2005, 12:41 PM

THANKS GUYS. ANYBODY GOT A NV5600 LAYING AROUND, THAT THEY ARE WILLING TO PART WITH???? JOHN AT FK9U812@AOL.COM

1969 GMC · 01-26-2005, 03:22 PM

the NV5600 is a dodge-only transmission, so check on ebay, a dodge forum, or a tranny shop. the 6 speed that GM uses is the ZF S6 650, which Ford also uses.

LT4XTREME · 01-27-2005, 12:43 PM

When I went to install a pto onto the Allison Auto in my 85 GMC 2ton I got the one I needed from a local place that services big trucks and builds beds (Benson Truck Bodies). I have seen straight cut gears and angle cut gears on the pto units. I think that the bolt pattern is common to be 6 bolt pattern. It should be on most trannies light duty and medium duty. The bigger bolt pattern should only be on the big semi type trannies. A neighbor gave me a pto that is 2-speed. I've never seen one before. What would a 2-speed pto be used for?

hgs_notes · 01-27-2005, 01:28 PM

Here is a new NV4500, they also have adapter kits sold separately.

One example I can think of is to run a PTO winch off of a transmission. Or anything off of a transmission, I guess. Transfer case PTO's speed and direction is controlled by the tranny, and tranny PTO's spin one direction and are controlled by engine RPM...but if you have a 2 speed then you have forward and reverse.

LT4XTREME · 01-27-2005, 05:51 PM

I'll have to look at it again, but I thought it turned the same direction just faster or slower depending on the gear. A forward and reverse makes sense for a pto winch. If you used the 2-speed to drive a hyd pump wouldn't the pump just put out more volume therefor making the equipment that the hyd pump is running (hyd winch or a cylinder) move faster. If I can find it I'll get a pic.

stllookn · 01-27-2005, 06:25 PM

How about an Eaton 2-speed rear axle? It was available in the 60 series trucks and would be really cool on your tow truck. It would up the capacity of the axle to 17,000 lb! I don't know if the gear ratio gets you there though but they were available on lots of the bigger Chev trucks and were electric shift.

NAW .. I THINK I'LL STICK WITH THE REAREND I'VE GOT. I REALLY NEED TO FIND A NV4500 OR A NV5600 WITH A CHEVROLET BELLHOUSING. JOHN
