[W126 Coupe] lazy transmission

[Vance Rowley]

Not heard from anyone in a while. Had problems with my email, so changed it.

Anyway, getting back to the subject, I have recently been having what I would call lazy shifting with the transmission. There is no slipping and seems fine on starting off as normal (in 2nd as it does) and also seems fine by flooring it to get 1st and then back to 2nd. But then (under normal acceleration) it can't seem to make up it's mind when to shift to 3rd, although this isn't as bad as it is from 3rd to 4th. Even after reaching a constant speed of say 30mph in 3rd (and the E/S switch set at E) most of the time it will just stay in 3rd and not drop into 4th. Sometimes it will, but most of the time I have to blip the throttle a little, then ease off for it to drop into 4th. Sometimes even this doesn't work. 

Summary is all downshifts seem fine and upshift from 1st to 2nd is perfect. Upshift from 2nd to 3rd is OK most of the time, but upshift from 3rd to 4th depends on what mood it's in at the time.

Should I just change my tranny fluid and filter, or is there some other explanation for this?

 

Cheers,

Vance
