I have a s40 1.9d / 2000 plate,
In the last month or so the car loses revs when changing up to 3rd and 4th gear, I can only get 50 mph max in 3rd gear 80mp in 4th.
The car has just clocked 185,000 miles
Its a great car but a pai at the moment, I've had a service including fuel fillter change added fuel cleaners to the deilsel all to no avail

The absence of 3rd and 4th is imposed by the transmission computer as a precautionary measure. The system has detected fault and rather than risk doing any greater damage has provided a limp home service. It needs to have a transmission specialist look it over and read the error codes. How do your transmission fluid levels look?

SOURCE: transmision starts out in 1st
Sounds like your transmission is in limp mode. This is a fault mode in which the
transmission either loses electrical power or the PCM deactivates all of
the electronics. The transmission will default to max line pressure.
The driver will have Reverse and 3rd, with manual 2nd available by
putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC
lockup will not be available. It will not hurt the car to drive it like
this for short periods, but use manual 2nd to get the car moving, and be
aware that the trans will generate more heat than normal while
operating in limp-home mode due to increased torque converter slippage
during 2nd gear starts and no lockup in 3rd gear.
The other from what you described, trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Thank you for using fixya and have your Safari scanned for the DTC codes that would indicate what issues your transmission is having to put you in to limp mode.
