I have recently purchased a 1996 Range Rover P38 that has numerous leaks and what not (which of course is normal). Some of its fluids seem like they need a change, primarily the engine oil and possibly some of the diff fluids as well. I was wondering what kind of synthetic motor oil some of you guys with p38s like to use as well as the recommended/required differential fluid. I am also looking for the breather plugs on the differentials to make sure they are not clogged, Haven't had much luck, does anyone know where they might be at? (they are probably right under my nose). That and I can't find any record of the transmission fluid being replaced... I was wondering if it would hurt anything if I went ahead and replaced that as well and also with what kind of transmission fluid? Sorry about all these questions, I do not have a service manual yet but, I just want to get it road worthy and have the peace of mind that I will not be experiencing any sort of catastrophic power train failures in the near future. Any input is appreciated.

 

i do not recommend synthetic, use normal, and change it regularly, as to the trans, good old atf, same for the tbox and the p/s. use heavy weight in the diffs, 80/90 or 70/90. if you dont know when the trans was done last, should probably change the filter too, there are a bunch of write ups on how to on here, its the same as a disco, just fill through the dipstick.

 

Here is a list for you to work from, there are a couple of items that might be different since I set this up for a Discovery, send me your tele number and we can talk more in depth.
