Good morning from here team,So I went back to the machine with another transmission oil pump,installed it and machine wouldn't even move again just making an attempt even a high revs. So I gauged pump at filter housing and it hit 360- 400 psi depending on rpm.
So I uncovered the solenoid and watched it as I engaged Forward/Reverse in gear 1,the oil that gushes out between solenoid 1 and 5 comes out very lazily,most times it doesn't even spit it out it just makes an attempt to. With forward and gear 1 engaged solenoid 2 & 6 were energised and magneting,but then I selected gear 2,3,4 and yet 2&6 were still energised, not shifting . The modulating valve bank has been serviced twice,since it wouldn't even move in the gear 1 it decided to engage, I got frustrated, unplugged all the solenoid, and hot wired it solenoid (2&6) .You needed to see the oil that gushed out of the hole and the power with which it moved with just a little pressure on the governor pedal. We had almost arranged for another tranny but thankfully we didn't.
Could it be an ECM failure?
Used select gear 1,3,4 previously, now only one and still wouldn't move.
Sorry about the long write up,I love details
