thomashawke · Jul 18, 2008

we have ford/newholland 95 7740 sle 7500hrs up.it started to grind getting it into reverse, so i had a look a found that the lock nut was loose on adjuster top of transmission.adjusted it, to where it stop grinding (lovely), but it started to grind going into forward after a few times of normal operation! is this a problem with adjustment or faulty solenoids , there known to give trouble so i have been told,had to rewire earths ,a lot were bad connection and broken.any information would be greatfully apprieciated.
thanks

No solenoids or earth connections involved here. You should try to fine tune the cable adjustment, but that may not be possible. Your Forward/Reverse synchronizer may be trashed. It requires a double split (transmission removal) to replace. The snchronizer was over $2000USD several years ago. The 1-4/5-8 synchronizer should be examined carefully, as it will be next to go. It would also be prudent to replace the piston seals and sealing rings in all 4 clutchpacks with those hours, given the transmission will be mostly disassembled. Just remembered there is a serial number break on that synchronizer, be careful when pricing/ordering parts.
