We got a lift in with complaint transmission fluid leaking from dipstick tube when hot, checked fluid level noticed was to high so we changed fluid and flitter. Made sure filled to right level then ran lift noticed fluid level kept increasing there is a hydraulic pump with another pump attached to it that could be leaking into transmission and raising fluid level but few made sure to rule that out, also we are using a Clark transmission fluid that is suppose to be compatible with the dexron3, the thing is the fluid level fluctuates and goes back down to correct level as well. Was told to check torque converter for slipping and raising temp of fluid causing it to over heat and come out but if that was case fluid level would go down to normal as soon as temperature did
