I have a 1996 300TDi auto not sure what you mean by what speed it pulls off at but as for the oil proceedure below...
Make sure vehicle is level, select Park and start engine. With engine still running at idle speed and foot brake depressed and handbrake on move selector to position 1 and then back to park.
withdraw dipstick and wipe clean, reinsert dipstick to check the level, used Dextron IID to top up. 1/2 pint of oil is required to raise the level from the lower to the upper mark.
I hope that helps, if you can explain the other thing I will try it and let you know, I think both our gearboxes are the same.
