WTF!? Tranny related question
My 240D has always started out in second gear, since the day I bought it.
First gear works just fine, but I have to shift it into L when I am sitting still, otherwise it never engages. The shift up from 1st to 2nd has always been extremely rough, it chirps the tires when it shifts (yes, I can actually chirp tire in a 240D, I kid you not) anyway, today I started it up, and when I went to pull out of my driveway, I was totally surprised to find that it started out in first gear and then shifted into second at about 5-6 mph....I had it in drive. every time I came to a stop, and then accelerated, it would take off in first gear, just like I would imagine it is supposed to. I got to my destination (a friends house, FYI) and shut it off. I started it a few hours later when I left. And, well, poo, it takes off in second gear, just like it used to. The anomoly had passed... But I can't help but wonder...WTF!? has this ever happened to anyone else? does this suggest a weak or worn out transmission? It shifts very smoothly and doesn't lag in between gears (unless I put it in L and rev it to the shift dots, like I said before) so I don't think it's going bad.

How can a 240 take off in second gear......can it even move?

Well, it does it. Certainly takes its time, but it does it. I usually (by usually I mean like 99.9999999% of the time) just throw it into first and shift up through the gears manually.

I think some of the older cars were supposed to start out in second unless you were REALLY getting on it. Does it go from second if you mash the pedal to the floor? Is your kickdown switch functioning properly??

my kickdown switch is 100% non-functional. I always have to downshift manually.
I hit the pedal fast and hard every time I accelerate....I mean, it's a 240D, if I didn't floor it I'd be getting one finger salutes everywhere I go.

shifting
quality of shift is controlled by vaccum from the top of the fuel pump..
starts out high and goes to zero... at zero you should be in high gear.. so your vaccum is probably higher in the car right now...the high vaccum is giving you a good well defined first shift.... ![]() |

I believe all of the diesels are supposed to start off in 1st gear, but the gassers all do in second unless you really mash the pedal.

my '79 300TD starts off in 2nd gear... i think the 1st gear starts are for the 200D and 240Ds.....though i may be wrong...

Both of our SD's always start off in 1st. Mine will stay in second on rare occassion if I come off the freeway and very slowly accelerate, otherwise it always goes to first, it even does if I am coasting to a light and it goes green and I hit the pedal between 3-8mph, it will drop back to first for a moment to get going....

This is all great really, but it's not answering the question.
The car ALWAYS started in SECOND gear, it didn't make a difference what I did. Then, all of a sudden, it started in FIRST, for seemingly no reason at all. .... ... ... Why?

A longshot, but I'll mention it. Suppose a PO had the trans replaced with one from a gasser. I forget the mechanism for controlling this, it's somewhere in the valve body. Might explain why it usually starts in second. Perhaps something in the valve body is hanging/changing that is beginning to have it start in first. Perhaps if you got the # on the valve body someone could identify it.

If you have a condition that is intermittent, whereby the transmission sometimes starts out in first and other times starts out in second, the most likely culprit is a valve body that is sticking somewhat.
First line of attack is to put some Trans-X in there and run it for awhile to dissolve all the deposits. Then do a complete fluid and filter change. I'm betting you will get first gear to properly engage, every time. |

Ok, I'll look into that, I work like two miles away from an autozone, so it can't be the hardest thing to take care of.
PS - I finally got a job. Woo.

Vacuum?
When I told my indy of issues about shifting with my transmission..I swear he mentioned something about a vacuum issue. He has tweaked some things with the transmission to make it shift at different spots. Mine always starts out in 1st but he's definately made shift points different with adjustment. Also, I've had the "modulator"?? replaced mine...about $100 and it shifts much better. I'm no mechanic but just thought I'd throw it out there.
Good Luck, T
