Rough gear change

[zico]

Hi guys

My 2001 rover 75 automatic just recently started to change the gears very violently. I changed the transmission oil twice. nothing improved. It used to be very smooth. The problem appered suddenly. I am in australia and its hard to get a rover specialust mechanic.

Hi Zico

First check if there's enough oil in the transmission circuit then check if there's any leak in the transmission tubes .If you transmission oil is to low or if you have a small leak in the circuit you can get enough compression in the transmission circuit so gear changing is bucking.

If the oil level is too low don't fill up but renew the whole circuit with a DEXRON III specification ATF (automatic transmission fluid)
I prefer fully synthetic ones like for example:

Try to find an automatic gear specialist around.

Hopefully this helps and you needn't to change the whole transmission.

Cheers Mintman
