Transmission Question

[300SDude]

so.......my W116 started only topping-out at about 40 when going up hills (I live in the mountains). I took it in to my mechanics and a hose had come-off the turbo. They re-attached it and everything worked well again. (It hasn't had an issue for about a year, but I don't drive it all winter).

Today I drove it to the casino and back (30 miles round trip), and I have to have it floored to get up the hill, and it's back to topping-out at 40 again. I checked the turbo, and everything seems to be attached OK.

Since I have had it, when you try and punch (floor) it from a stop, it tends to slip a little between first and second gear, but if I start-out normally, and gradually pick-up speed, it shifts just fine. Is this a major transmission issue?

Not that I am trying to burn rubber in my diesel, but when my partner drives it, she doesn't like the way it shifts and picks-up speed from a stop.

I guess I am just a pansy and just drive my baby slow wherever I go, lol. It doesn't really bother me the way it shifts, but is it something I should have looked into, or is something simple?

Thanks for any advice.

It could be many things. Are you getting full throttle? Get one of your girls to floor it when the engine's off to check the linkages. Why did the hose come off? If it's gone hard it could've split somewhere else....

What's the colour of the trans oil like? When was it last serviced?

I've never done anything with the transmission, or the oil in it. It's red, that's about all I know, lol.

It would probably be advisable to change the transmission oil and filter. You might also have a look at the adjustment of the Modulator valve - if it is out of adjustment, you can get slurred shifting of the gears. Regards Styria
