Thanks Randy, but I am not sure I understand the grass thing. As I understand it, if the C solenoid goes bad, then the car is in 50/50 power distribution all the time. So if that is the case, it would seem unlikely that the front tires would spin. What I was wondering was even tho the light is coming on, maybe in fact the transmission is still in the 90/10 mode rather than the 50/50 mode and is there any way to tell? I will go ahead and try the grass thing anyway and let you know how it goes. The estimate I got was $1k to replace the solenoid assuming nothing else is wrong, so sounds like you are right on about that.// Jack
