  1. air compressor let go and leaked oil in the air system. how do you clean the oil out of the air system?
  2. i do that also. sometimes i hit the splitter just before i move the shifter and have no problems with gears grabbing but i usually split passing through neutral. only gears that grind when splitting and shifting to the next gear are 3H-4L and 7H-8L. it doesn’t matter if i preselect or split going through neutral, it still grinds. i can smoothly split passing through neutral to the next gear or split just before i move the shifter with all of the other gears with no issuses.
  3. i plan to. i just wanted opinions on the issue.
  4. it has a 2 year warranty and it was installed a few months ago and i do split passing through neutral and the gears still grind.
  5. had a reman 2180b installed and shifting from 3rd high to 4th low and 7th high to 8th low grinds. every other shift slides and clicks right into gear.
  6. whenever i have to firmly and quickly use my brakes, i hear a loud thud sound and my truck pulls hard to the left. my mechanic cant find the issue. could this just be a bad brake chamber?
  7. terminology was wrong when they were saying the synchros were bad. the clutches were worn amongst other things. $5200 was the cost of the reman.
  8. the problem was the gears weren’t meshing together when splitting from underdrive to direct and direct to underdrive while in high range..no problem with gears in low range. splitting in high range would put the transmission in neutral and or neutralize then knock into gear. i was told that all of the synchros were worn and thats what was causing the problem. i put a reman in because it wasnt going to cost much more than repairing what i had. now it shifts fine in every position.
  9. no grinding at all. i range shift, move the shifter, then split.
  10. im going to call the company that did the transmission work and relay what you guys are telling me cause i was told much different. if my problem with this transmission was gear splits not meshing together causing neutralization and or rough engagement, what do you think happened to cause this? im now understanding what mach tech is talking about and didn’t at first due to what i was told previously by other people.
  11. in an 18 speed? why do you think i was told that there is 6 and that they were all worn?
  12. so just range as in high and low..not underdrive and direct?
  13. so how many synchros are in this transmission for splitting gears? the only problem ive had is splitting from underdrive to direct and vice versa. never had a problem with high and low range.
  14. well wont a bad synchro cause a a splitting problem? mack didnt come out with an updated synchro design? i was told there were multiple synchros that were worn out. im not disagreeing with what youre telling me. im just repeating what i was told and i dont know much about transmissions from a mechanical standpoint. also, the power divider was accidentally engaged while it was getting worked on. the switch label is worn and illegible and i couldn’t remember if it was supposed to be in the forward or backward position on the dash but did notice that i didnt think it was in the position it was in when i dropped the truck off. i switched the power divider from forward to backward as in “out” and now it shifts just fine. no problems with the transmission and luckily, the power divider still works.
  15. so is the transmission going to stay this way unless it gets pulled apart again? or does it need to be broken in?
