Guys, help please; After starting, select 'drive' and move off. Into 2nd gear and any acceleration and the "thrust" stops and engine idles, 4 seconds no drive force and that driving force cuts back in for 4 seconds - then repeats. If I try 'D' (drive) and let vehicle idle off the mark, it will change into 2nd, then 3rd - but any attempt to accelerate, and engine cuts-out all together. Is the problem low auto fluid (which is hard to dip accurately), or do I have another evil lurking. Help most appreciated, thanks.
