well luckily my boyfriend goes to diesel mechancis scholl and i have been to automechanics school aswell. they let me go into the shop and work on the car with jesse! today we are going to change out the tranny fluid and filter. when i bought the 300 sd the oil was changed that day or so he told me. i still feel like it would give me a good peice of mind to change it my self. i got a vaccume diagram off of this forum from phantom (thank you sooo much) it makes every thing easier.i have noticed some rubber fitting that need to be replaced and the white hose that goes from the central plug to the Y was completely broken! thank you all soo much for the advise i really appreciate it!
