MARK thanks for your offer but made a possible breakthrough yesterday i had a rov 45 with stepspeed available for comparisons.
using T4 one of the sub system tests was for checking function of the park/neutral switch,this constantly failed the test on the 25 but when carried out on the 45 it passed every time, then the strangest thing happened i began to check again the inhibitor function to see if the starter would only crank in P and N this was confirmed but with gear lever in the R position and ign key turned to crank position no crank but i noticed the R symbol in the instrument pack was being displayed,i cant explain why this was so anyway i shifted through all gate positions and all symbols were displaying this wasnt occuring as previous posts will testify to.
any way took car on r test and every function working in full auto mode ,sports mode and up and down manual shifts.
since then i have studied circuit diagrams but as this is very complex going through many components it is impossible to come to any certain conclusion so whil have to monitor over next few days, at least i can rule out any mechanical fault in CVT transmission.
GEOFF.
