1990 300se transmission slow to shift in morning

[xwingftr]

Hello everybody,

During first start of the morning, no matter what the outside air temp is, the car is slow to shift. It does it about 80% of the time. I rev it up to 3K, at times holding up traffic behind me, until the car decides to shift from first. From then on it does fine the rest of the day? The gearbox has been serviced, oil and filter, and the car has 115K miles.

A local shop, based on what I described above, already has quoted me 2,800 for a new transmission. I was told not wait too long or it will make matters worse? Anybody have input?

Thanks,

Hi Television,

Please could you give more info on the shift valve kit - can you include a link? Is it easy to fit?

I have a similar problem to xwingftr, but my problem is selecting reverse from cold.

Thanks

how long does it take before it'll shift up? Sounds like the cat-warm up delay to me.

Sorry for the late reply. It takes a couple of blocks, maybe a quarter mile at times. I'll keep the RPM at 3K until the car lunges forward as second gear kicks in. From then on she shifts fine for the rest of day. On another subject: the car is getting 21mpg (mostly hwy) does that seem low? Thanks!

yup, this is the upshift delay to warm your cat up to operating temperature more quickly. Try letting it warm up a bit before you set off, then just driving quite slowly (if you can without holding traffic up) for a couple of blocks, it should help things warm up quicker.

21mpg sounds a tad low for your car if it's mostly highway, but not far off. I got similar in my 300E (same engine)- they're not economical!

Thanks Chaz!
