Clonk and jerk when cold and stopping
I hope someone can help me.
I have a 89 Falcon wagon 3.9, done 233K km, where I had the selector seal changed. approx a week after that it has started making a loud metalic clonk and a jerk when going from higher speed down to approx. 15 km/h fx. stopping for a red light. It only does it while it is cold - shifts fine when warm.
I dont know much about cars, so here you have all the info I can think of:
1: The selector seal renewed
2: Transmission oil level quite high
3: Had to jump start it
4: only a problem the first 7-8 km.
I hope someone can help me, and maybe tell me a little about the consequences of too much transmission oil. (I have searched all over the net)
