I am looking a 88 model d4c that has been setting for maybe 5 years, I cant get the straight of that. We got it started without any problems,but it doesnt even try to go into gear. Check the filter,its clean, screen is clean, full of fluid. I dont have a manual for it' Cat dealer says the drive shaft should turn when its neutral even if the torque or trans is bad and it dosnt. I stuck a screwdriver in it and it didnt turn. Also her brother has never wanted her to sell it. Is there anything he could have done to lock everything up? One last thing. We didnt have a key, had to jump it over if that means anything. Thanks and have a Great Day
