my automaic megan 1999 124 thounsands miles gives me trouble on long trips it feels like it is droping down gears and going to stop and then it starts to slow down and take off quck and body got and ideas
check auto trans fluid is up to correct level and no oil leaking from gearbox sump, cos if not enough fluid present in gearbox, it will "slip" in and out of gear.
if o.k. change fuel filter.
