I am working on a m126x tractor it was in the field bush hogging all day, it was shut off that evening and the next day it wouldnt go into 1-4 gear in high or low range, forward or reverse it flashes a R-35 code. 5-8 gear works fine. i looked the R-35 code up and it says "solenoid proportional pressure reducing valve (main shift L)". Ive checked fuses,looked at the wiring, replaced the ECU main, replaced the transmission wiring harness,replaced the main shift L solenoid with a new one and a known good one. Kubota has looked at it twice and ive spent ridiculous amount of time crawling around on this tractor i am stumped!! Any help and advice would be greatly appreciated.
