I hope one of the Maxuum experts may be able to help as I have just about given up. I will try to keep this as brief as possible. Crown wheel and pinion replaced + charge pump and main hydraulic pump + plus various solenoids etc. When cold powershift works normally, only the loader is slow to lift. After approx. five miles on the road transmission light comes on and there is no hydraulic pressure at all and of course no travel. Any idea where to look next?
