Hi guys I'm having issues with 4 gear synchro crunching gear so guess it's a box out and rebuild job.the question is can anyone point me in the right direction to anyone that could help .I'm in the UK in the SW thanks

 

any help welcomed guys .

 

I would first try flushing the gear oil, check for particles, then refill
with Amsoil, Redline or another high quality gear oil. Not M1. I’ve had best results with Amsoil. Good luck.

 

I think it might be passed the flush the clutch is going to be replaced so think it probably best to get it rebuilt .do you know anyone here that rebuilds the boxes
