Full Floater

Here ya go!!! She aint that pretty but that's nothing a fresh coat of paint and some newer tires and wheels wont fix

Thanks so much for the positive feedback, im very happy with it thus far, only 225km on it. I will practice the shifting more and more in hopes to get it mastered. Ok, that makes sense to me mrsmackpaul. But just to clarify, if I want to shift from H to direct; I would maintain my throttle input, preselect the "D" and then increase the throttle input by the 400 revs to match that gear and it should go in? Is it normal and typical for them to growl and grind just a bit when splitting? I have yet to get a perfect no growl shift, but im getting close. And yes, mine is very whiney in 5th over, much louder then a fuller trans no doubt. What fluid to these trannies like? And how about the 300 hp Mack engine? Are they a reliable engine? Any maintenance tips or things I should look out for? It seems to really like being around 15-1600 rpm. Do you guys run a lube additive in your fuel? Mine runs at around 160 degrees and climbs to about 180 on hills and about 200 if loaded with some weight. I have not maxed it out yet for weight.. Is that about the right temps? Mine is a water truck, 4000 gallon with a PTO pump (which has a broken driveshaft at the moment) I'll get pics up this week.

Bought a 79 RS600 today. My first R Model, in fact; its my First Mack. I have driven R models a bit in the past and have always liked them. I have the E?300 in mine, its a 1983 Model engine and he 12 speed transmission. There are no tags or shift pattern stickers inside saying which tranny it is but im assuming its a 12. 5 main gears with a Direct and OD and R on the air knob and the "bull low" stick next to the seat. I can shift it alright but I think Im missing something,...im still grinding more then I think is normal. What is the proper protocol for shifting these things? When you upshift from direct to high, do you simply move the selector knob towards H as you get off the throttle? Do you clutch and get off the throttle? And downshifting, do you move the selector and throttle up to match revs or clutch and throttle? And upshifting the main gears, do you preselect D as you prepare to upshift to the next gear??? Any info would be great. Thanks
