My problem was that the jacks would not come up high enough to get the light to go off and sometimes when the light did go off the alarm would sound when you put the tranny in drive. At first, not knowing what to do, I put a car floor jack under each jack and gently put it up with the jack. I found the fautly jack on my second try--the light went off--and stayed off. Closer inspection indicated there is a grease fitting at the bottom of the each jack, a little grease fixed that problem. Anyone know how it check the fluid level in the system? Thanks, Ron
