hi all first post here i have a 956 4wd here with a problem with the pressure lube warning light, when the tractor is in 2wd the trans lube warning light will come on after a short time, when switched to 4wd the light goes off instantly, i pressure tested the pump it was putting out 18 bar, would i be right in thinking it maybe a leak or fracture somewhere in the pipework in the trans, the tractor got stuck in 4wd a few months ago i pulled out the lube pump suction filter after there was only a small amount of metal pieces on it, i have the 4wd propshaft off at the minute and the solenoid electrical connection disconnected the warning light works fine now does its normal thing when the key is turned before starting the engine. sorry for being a bit longwinded thanks for any replies tom thanks for the welcome sven hope my post is a bit better now. thanks for any help
