luigiestrada Posted February 16, 2013 Share Posted February 16, 2013 I have a 2004 granite with an automatic transmission and i'm trying to convert it to standard, the transmission that it has at the moment is a MACK T309 and I was wanting to know what I can replace it with? If anyone have some knowledge about this please help me out. Quote Link to comment Share on other sites More sharing options...

jakebrake86 Posted February 16, 2013 Share Posted February 16, 2013 Yup, T309 is a manual trans. Just drove one the other day. 7 years old and 600,000 and it's jumping out of 4th and 8th gear. If you meant you were going to swap in a T309, I think I'd find something else, personally. Your best overall bet would be just sell your truck and find one spec'd the way you want it, unless you had a wrecked donor truck you could rob parts off of, such as clutch pedal and linkage, floor board, bell housing, transmission mounts, driveshaft,etc.....

luigiestrada Posted February 16, 2013 Author Share Posted February 16, 2013 Sorry Mack T309 is one of my options to put in the truck but was thinking that I could find a different brand of transmission that would not cost as much. @bigdog that's the state the truck came from.

Superdog Posted February 16, 2013 Share Posted February 16, 2013 if you got an '04,you got bigger problems to worry about than a transmission. Quote Link to comment Share on other sites More sharing options...
GearheadGrrrl Posted February 16, 2013 Share Posted February 16, 2013 T309 would probably work, but you might want a transmission with deeper reduction. Quote Link to comment Share on other sites More sharing options...

Green Dash Posted February 17, 2013 Share Posted February 17, 2013 At work we had an '06 with an Eaton Ultrashit that no one wanted to drive because it was difficult to back up while trying to maintain enough rpm's to engage the clutch without having to go too fast. They eventually decided to swap it for a 9 speed Fuller and it took weeks for our shop to get it to run right. I believe it had something to do with the ECM not being able to recognize the new tranny. Quote Jim Link to comment Share on other sites More sharing options...
realwolfdaddy Posted February 17, 2013 Share Posted February 17, 2013 T309 would probably work, but you might want a transmission with deeper reduction.Why did they order Macks with auto transmission? For Unions, with female drivers. My dad lost an account because the females at a company couldn't drive dm Macks with six speeds . The company instead had to go back and useing Ford f600s with 460 gas engines with c6 transmissions and also had to buy d5 bulldozers to push these truck up an incline they had. The females complained and the union stepped in. btw the fords were only lasting a year and had to be multiplied times the number of Macks to move the amount of dirt that needed to be moved.

rsb502 Posted February 17, 2013 Share Posted February 17, 2013 What's wrong with the automatic? An Allison would be my choice if I bought a new dump truck, they do much better off road, paving, milling anytime you needed steady low speed performance they are the ticket. I know someone will say its a girls truck and all I can say is try one of each and you'll see what I mean. If I was to buy an otr truck its completely opposite id go with a 13 or 18 manual, I do not like the centrifical clutch automated manuals at all. If you swap it id go with an 8LL they are plentiful and cheaper than a 309 or t310 which would be my Mack trans of choice for a dump. If you decide to swap you will need to have the ecm reflashed or replaced with one from a manual there are sensors it relies on forcertain engine parameters, the tcm will come out with the trans, then you get to change the motor mounts, speedo adapter, center floor panel, add a clutch pedal assembly and cable, drive shaft and that's just the beginning.

storkmack Posted February 17, 2013 Share Posted February 17, 2013 For the majority of the work we do, if I were to buy a new truck it would most certainly be a MP7 with a M-Drive. I will more than likely never see a "new" truck, but our drivers will. -Brad Quote Link to comment Share on other sites More sharing options...

rsb502 Posted February 17, 2013 Share Posted February 17, 2013 Automatics have come a long way, almost 90% of refuse, concrete trucks, municipal trucks and buses are Allison automatics. I remember the first one we had in a bus it was a pos but now with a 3000series 5 spd they last the entire 15 year life of a 90 passenger 40' long school bus here, as long as you do the required maintenance that is. I know we change the external spin on trans filter every service and change the fluid and internal filters every other year and have 0 issues with MT643's and pts3000 series, the2500's are touchy they don't like that much weight (90 pass blue bird is around 34000 loaded). I am still not extremely impressed with the Mack/Volvo auto, the single countershaft is a fairly weak design and from what Staxx has told me when one thing goes the whole this is a boat anchor. I like the features of the M drive and the gear ratio steps are great with a low rpm high torque rise engine, I just think for longevity's sake I would stick with a manual OTR. That's also the reason I don't think an M drive will hold up to a heavy application like a dump truck, look at the internals compared to a T310 or 8LL its just not as strong. I was completely against automatics for years but the last few years have proved me wrong they are the way to go for an on/off road application and if those that always seem to have issues weren't beating them to death and running them to failure before doing maintenance they would last for them too. I have learned a lot watching the trucking industry in the last 10 years, lots has changed and if you are willing to try the new things most of the time they work out. The Industry spends millions in r&d for these products give em a shot, do your own research and go in with an open mind and you may be surprised what happens, I wasOk off my soapbox for a while! 1 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment Share on other sites More sharing options...
