slowing down to about ten miles an hour from say 30mph, or any speed,the
transmission clonks.at this point hydraulic the pressure of the
transmission fluid drops to zero. it appears that the brake band is being
released suddenly.this does not happen when auto box is in third gear.
please can anyone help? or let me know where i can get expert advice on
this. many thanks, Eliot.
Are you sure it's the transmission clunking? Sometimes the driveline

check the vacuum pressure and adjust the modulator.
If you have turbo, you need to check the vacuum pump and then adjust the
