I have a 2000 Cheverolet that I just had to replace the clutch in. After test driving it, it appears that the synchronizer is messed up on 3rd gear as I have to double clutch to keep it from grinding.
My question is, what kind of cost am I looking at to get this fixed? Would going for a complete rebuild be the best thing?
Possibly anything I can do to fix this problem myself?
The transmission is a Eaton FS4205 B 5 speed. |

I currently have all automatics in my fleet but when I had straight shifts we had little problems with the internal parts of the transmissions. That being said I am wondering if you have a problem with the clutch not disengaging all the way. |

We always did our own trans rebuilds in the GM buses. Because of the type of use that a school bus sees, failure of the sycro units is common if the transmission is not double clutched when shifting. If you are using a new spicer clutch the chances of a failure in the clutch is slim. Many of our suppliers will refuse to handle reman clutches because of the high return rates. |

Prolly a blocker ring. All of our manual trans tools got donated to the local tech school. About 8.8 hrs for R&R and overhaul, plus parts, fluids, etc. |

Sounds like you just need some new synchros. Rebuilding it yourself if done checking all clearances and endplays according to the manuals can save half the cost of a rebuilt unit. I havent rebuilt a manual in ten years but I know getting a new shift tower was always required if you can feel any twist play in the shift lever. |

Make sure the clutch hydraulics have no air in them before you do anything. |

These buses us a cable operated clutch. The trans uses two sycro units 2nd-3rd & 4th-5th. They are replaced as complete units and cannot be repaired. The only special tools required for a rebuild are a dial indicator and a micrometer. As long as you don't need a shaft or gears you should be dollars ahead to do the rebuild yourself. |

Sorry, he didn't specify, so I thought he might be working on a smaller truck. |
