with the price of trucks today, do you buy an older one and try to build what you want. I wish I knew the answer...

the T300 is a smoother shifting tranny, with shorter gears.. as you know. It would be cool if you had access to a 7 speed for practice to see if you like it.. When I drive them, I count in my head, 1-1000,, 2-1000, shift. I double clutch so so when I come out of gear I say 1-1000, (nuetral) 2-1000 into next gear... it's silly but it works for me,,, then after a few minutes i'm back to having a decent rhythm I still scrape a gear here and there. The blue button on the shifter for the 7spd. is for low and low-low. you start in low-low, then go to low. if you need to use low range. then when you change the range you have to flip the blue button up as you pass through nuetral, because it is not synchronized... like the 9 spd. you have...

the seven speed is a tough tranny. but patience is needed to drive it. they do not shift as smooth as an Eaton and the time between gears is long. that tranny is a 2070... probably has 4:17 or 4:42 rears.. it's a strong combo, just slow.. I dont mind 'slow' it's a truck.. jojo

Tough one to answer because of the un-known's.. I guess if the seller would allow you to drain a little gear and tranny oil(before the truck is cranked/moved) into a clean pan through a small kitchen strainer to look for chunk's, and oil condition, you can take it from there. I have seen many of these trucks with over 1 million. it ay be hard to get good maintenance records, because the truck may have been owned by several people.. I hope some more opinion's are posted... jojo

here are the fuse legend's... A little hard to read, my hands were dirty when i made these copies in a hurry... jojo

it's basically were the wires make a change in direction, like through a switch or relay or module.. I'm a little rusty, but that;s the best way I can explain it. the pin # and ECU plug # will stay the same on the circuit, for example EJ1 26, is Engine module, J1 plug/connector pin 26.. or VJ1 12, is Vehicle ECU connector J1 pin 12.. I'm sorry if I'm not making sense, it's hard for me to type this, it would be easier if we were together looking at it.. jojo

isnt the 5th wheel reversed for pulling sleds at truck pull's? jojo

I've had these for about 20 years. One of them is perfect. There are Book number's for you to use to try to find what you need..

just a thought.... If he marks the heads of the pump gear bolts, then puts longer bolts in there place, then loosen the pump and slide it back on a guide bolt in place of the econovance mounting bolt's? maybe with a a flat screwdriver he can sneak some Mack Gray RTV. after a good cleaning with brake clean.. What do you think Glenn?? Jojo

This one is happy right where he is.. Jojo

WE have 2 inches of snow so far today, 1/16/22 9:30 am.. My Boys love it!! Jojo

Spoiled Brat's !! Jojo

we have 2 superliners with a unit that goes under the passenger seat and the condensor with the fan is mounted on the frame behind the cab on the left side. you use the compressor on the engine and run long lines. the unit under the seat has the blower and vents in it. I put a small fan in the cab to circulate the cold air better. it is a good set-up not perfect... but good.. We are in central N.C. we get many 90+ degree days.. I will be back at that shop on Tuesday, and I will try to get the name and part number.. I posted this because the grill condensors are expensive.. the A/C system was 3/4 the price of replacing just the grill condensor.

I'm thinking you may need to remove the springs and frame hangers and take to a shop with a press.. I have done then on the truck and I had to get creative to get the new ones in. the old ones are usually so bad that the pin will come out and then I cut the rubber and bushing with a sawz all, yes i do nick the boss but I had to do what I had to do.. then I buff the boss with a flapper wheel. then I fight and curse trying to press the pin in the hanger.. in recent years i send them out to get pressed.. I wonder if there is a mobile service in youre area that has a portable hydraulic press.. jojo

Glenn is right ... just check the level in the bowl, at the rear plug. the rear end is splash lubed and there are channels cast into the inside of the carrier housing to direct the oil where it needs to go.. jojo

Here they are... it's a copy of a copy i made 22 years ago.. jojo

some time's, I lube the u-bolt threads then back the nuts off and lube the nut and washer surfaces then retorque them. then run the truck to see if the springs are shifting, sometimes you can hear a popping sound when turning, that means they are shifting side to side. I said 3 spring leavves, you have 4... sorry about that.. between the axle beam and the block, should be a thin wedge. if so, does it look crushed or worn? I think the u-bolt's are 7/8" I will get the torque for them and post it.. jojo

Yeah, I'm sorry if I'm harsh.. I just think about owner operators who need to get the most out of thier trucks and this tranny/clutch, has many issues.. I have pulled many of them before 300,000 miles.. you are doing good if it's the original tranny and clutch.. jojo

I'm guessing you have #14,500 front springs, 3 leaves... the band clamp on the end of the spring pack is basically an indicater for shifting spring's. Are they shifting? if so ... jack the truck up and support the frame. crawl under there with a sledge hammer and try to straighten the spring leaves, if you do... they are loose.. probabley 1 1/8" socket put the toughest 3/4 gun on it or 500lbft or whatever you can pull... test drive the truck "at work" and re-check e'm.... jojo

just had another thought.... So our supplies of ALL KIND'S are in short supply... You reckon it's because of a 'War effort'? I'm no history buff... But what I think about is 1943 in the U.S. when the U.S. Mint made pennies with steel because they needed the copper for the war.. Is this B.S. we have similar issue's, because of the scope of highly intelligent weapons and they are messing with other supplies, like food,, and fuel,, and blaming it all on the 'New scapegoat' COVID ? Am I nut's? Jojo

well I found 2 pic's just not with him in my boxer shorts... jojo

Yep... The Cone of Shame.... 1 of my boys, had it plus a set of boxer shorts on after some rear end surgery. jojo

I hope i'm following correctly... Did you swap a known good EUP with #4 to see if the issue follow's the EUP? jojo

M-drives don't make it to 750... they are junk...

I forgot to add, that there is a small air tank under the driver's,,,, I mean 'sitter's' seat, that is for the tranny...you may need to clean it out.. jojo
