As I mentioned in another thread, I picked up this really nice '93 245.

I have a couple of questions about it. It has the M47 transmission, which everybody seems to hate, but I think I remember reading that the later year M47s were more robust??? Is this true? If so, why?

The previous owner is running Amzoil ATF in it, but admitted to me he only changed the fluid twice in it's 130k mile lifetime. (He's the original owner.)

Meanwhile, he said he has never changed the rear differential lubricant, which leads me to question #2: What kind of lubricant should I be using in the rear end? Again, I think I remember catching word that Volvo had an optional limited slip rear end in 1993. Is there a way to tell what version I have and if so, what type of lubes are appropriate for either of the two types?

He ran Mobil 1 10w30 in the engine for the car's non-dealer-serviced life, and the engine is quieter than any of the 7 other 240s I've driven.

I want to go through the car and replace the lubricants, but I want to put the right juices in. Amzoil ATF+ synthetic makes no mention of being Type F compatible, which is what the owner's manual states to put in the gearbox.

So I'm just being cautious before proceeding with the big changing of the fluids. Thanks for any info!
