My friend's 1991 M5 is on its 3rd tranny in 75k miles.
Of course the 3rd time was under warranty.
My dad just had the pump in his tranny replaced, and it cost him less than $1700 on his 94 SL600 with 63k on the odo. when the dealer wanted over $3k for a new tranny.
At least My dad let me borrow his SL while my car is in the shop. I called him while he is on a business trip, and asked him, at first he didn't want to, and I was fine with that, but the moment I told him I'd go get a rental he said go ahead and use my car.
So At least I get to cruise top down in the SL during this beautiful 80 degree weather in Los Angeles.
Of course the stares from people because I'm in the SL is always a pick me up. it helps me not think about the cost of my repairs.
At least my mechanic said everything else was in great shape.
And my fluid level was fine, and the fluid and filter were all ok, so I know it wasn't from that.
Perhaps the previous owner negleted it or just drove the hell outta it....
