Slick 60's

Anyone on here done it? It seems like my best option for a truck tansmission with an overdrive.. any pics?

Never heard of slick/ NV4500 swap in Ford . My question would be what transmissions would fit your needs pavement queen or rock hauler? Seems that many overdrive trannys might meet needs for hp and torque of engine?

Other problem is that every one is looking for the NV4500 so they are expensive and scarce. I have looking for one for Chevy 4x4 1 ton with 4.10 gears without success .

You biggest issue with using any other transmission with a y-block is that the input shaft is longer on the y-block transmissions. You can bolt a lot of transmissions to the bell housing, but they won't enter the pilot bearing/bushing on the drive shaft. Mummert machines bellhousings so you can bolt up a 5 speed. Are you considering the NV4500 because you are going to be pulling heavy loads?

correct y block od trans is the clark medium duty trans found in f600,700 etc fits right in no shaft issues. i will need to look up the number again, theres 2 of them 1 is od one is not.

ya I found a regular 5 speed a while back in a 63 f800...hd lincoln style y block, couldn't find the ID plate or numbers, if I got a good deal I might go for a clark 285 vo...but for parts availability...if I swap I figure why not go 30 or so years newer, and make a shift cane that looks like my T98 cane...looks stock for the most part...and its got an od...at 55 I'm at 2200 rpm...and i have 2.25 rear gears....dads always questioned if 4th was really a 1 to 1 in our T98

no to be honest...i dont intend to pull much...but I ju st like the flexibility to be able to use it as a truck if i need to..other wise I might go with the t5..

A T5 will do occasional F100 level work with no problem at all. The T5 really is a good compromise. 1st gear of the T5 will be geared better than a 3 speed for getting a load moving. It won't be as good as the NV4500 or even the truck 4 speed in that aspect. However, since it will be primarily a cruiser, all 5 forward gears will be more practical on a day to day basis with the T5 whereas the truck transmissions will have a 1st gear that you will use only when pulling a load.

I agree, a T5 with 3.50 gears seems to work just fine for street and highway, not sure about pulling trailer loads with it just yet. The t98 cane whittles down to half shaft and mates to the t5 shifter just fine, but spend the money on one with a tighter shift pattern, it will feel loose and sloppy with a factory set up even if you tighten it up with extra springs

well ill have to do some investigating then, on the t5 route...then again a while back a yard told me that they would sell any tranny for $150/200 somewhere in there..so what ever i could find first maybe...ill have to do some lokking and weight out everything like i said..hmm

Understand that a $150/$200 transmission is going to need a complete rebuild. You could get lucky and get a good one at that price but don't count on it.

very true...if im lucky i can get one that just needs some top end work..but if its as good as my t98...and its in really good shape..it will do for a while..and my t98 may have been rebuilt...but i doubt it
