    R-611T== 673T with a roadranger ??? Thanks for picture. hope more pictures in future;; interior/ engine compartment.

    So it does have the 673t but I’m sure what the road ranger is. The transmission is a Mack 10 speed and I believe the model of the transmission is a TRD(L) 722(0). I’ll definitely be posting more pics in the future as I get around to cleaning it up and fixing things.

    Been contemplating this change on my truck for years.  Haven't wanted to cut the original yet, been hoping to find a used SS model that might fit well.  I know Watts used to offer a dry filter set up but is a bit pricey these days.

    I know oil bath is supposed to be better but I know my 237 sure does pull a lot of oil through the intake pipe.

    Seeing how I plan on keeping it all stock then I might just leave it the way it is.  Keeps with the authenticity.

    Take off in a gear that you don't have to ride the clutch.    My B can go as high as third low bobtailing.

     

    Whats the saying.....ass for every seat?  Looks like that seat had every ass in it!!  Lmao!!

    Yea I hate riding clutches cause I’m the one that replaces them lol.  The seat met its demise at the hands of a couple of raccoons that got in the cab and couldn’t get back out. They died in there but not before they shredded the seat. The seat was probably wore out but not in pieces haha.   Luckily everything is metal so they didn’t hurt anything else.

    10 speed direct.  That's the "Duplex".  You can split each gear for a total of 10 forward.  2 reverse.  So, yes, a TRD-72 or -722.  Probably -722.  Could be the "L" or not.  Depends on the case material.

    the 9 speed (-720 or 7220) was direct in 4th, overdrive 5th, so you typically skipped Lo-5th (duplicate of Hi-4th).  Just went from Hi-4th to Hi-5th.

    Mack boxes are "married" boxes, with the compound bolted directly to the main.  Not remote mounted like a typical "Brownie" (Named after the Brown-Lipe brand).

    I always loved the split-shifting instructions they gave (like on the bottom of snowdog's post).  They show shifting the main box first in all cases.  I never found that to be true.  If down-shifting the main and upshifting the compound, I found it better to upshift the compound first, then double-clutch and downshift the main last.  Reason is simple.  If you have enough RPM available to downshift the main first, then why even bother splitting it!  Just downshift the main and put your foot back in it.  So, I always upshifted whichever box was going up first, then downshifted the other.  Worked better.  If you learn really well, you do them simultaneously.  But, when you miss one, it's hilarious for everybody else to watch as you try to get them back in, stop, and start all over.  Ask me how I know that!

    In reality, you don't need to split the gears most of the time.  You can usually stay in Lo, use 1-5 in the main, then shift to Hi.  Probably start off in 2nd even.

    Anyway, I love that truck.  Steel dash.  Green interior.  2 sticks (a Mack-must!), and a single axle.  Just love it!  Kinda jealous!😁

    Thanks for the info.  I also love this truck lol it was love at first site.

    I would suggest that you sprayed for hornets They set up camp in my DM every year on the clock ha ha that thing looks amazing best of luck to you partner you’re really not going to need a whole lot to get her in shape from what I see the truck is in a lot better shape than mine is…  mine needs a lot of work but thank God it’s all a lot of small stuff just mainly elbow grease bob 

    I’m not to worried about the hornets, nothing some spray can’t take care of.  Mine has a Mack 10 speed, it’s a 5 speed and two speed brownie.  Not sure what the model of transmission in it is, I’ll have to figure all that out later.  Good luck with the work on yours, hopefully I’ll be starting on mine soon.
