Hi my name is***** will be glad to try to help. But first could you tell me if you have the shop manual handy for your serial number machine as I have experience on these machines but I would need the specs from your manual to help you with troubleshooting this. There are a couple of things. 140-150 seems low to me for pressure. Do you have the specs. If the pressures are low and all the solenoids are powering up as they should in each gear position you could have either internal leakage in the transmission still, a control valve problem, or a weak pump. Let me know if you have the manual and if not I can likely help you with a PDF format one available for purchase so we have the specs to troubleshoot this. I worked at a JCB dealer and also was field service for Cat. I will be glad to help you with this.
