Endt 675 Allison Trans Adapter

Recommended Posts

Someone on eBay has what I believe is an air shift 6 speed. Its only 250 bucks but he is located in Florida. here is the link

That 6 speed is a TRXL107A, direct in hi gear.

Maique stated that he currently has a TRQ7220 in his truck, which is a double overdrive transmission with .70 overdrive in 5th hi.

If he were to remove the quad box and install that 6 speed, the road speed in hi gear would be greatly reduced.

Running with that 6 speed in hi is direct drive.

Running the quad box in 4th direct is direct drive.

Therefore, whatever top speed is obtained in 4th direct with the quad box, will be the MAXIMUM road speed in hi gear with the TRXL107A

Of course the rear ends could be swapped for the proper ratio to work with the 6 speed, (Usually 4.17) but this is starting to get expensive!!!

not to add to the confusion, we have two dm 600's 79 models, allison 750's with 4.64 ratio..nothing, be it my V8 Superliner or my 550 cat powered KW will beat this trucks off the line...it amazing to me ..I guess the folks that shoot them down generally have never had one..Next time you and your high powered truck are at a stoplight besides a underpowered school bus..try and keep up..you will be suprised..the automatics are neat.

Ive got a t2050 .....

Well, at least that's got a .60 overdrive, but the low gear ratio of 5.24 will certainly leave him paralyzed when off road.
