I would look at the ignition system (spark plugs and wires) for any signs of weakness, arcing and voltage breakdown. Assuming you have an automatic check the line pressure adjustment as per G:05:03. It is very likely that you have a defective trans filter or low fluid. It is very bad on the trans to drive it if it is slipping. I would also have the fuel mixture checked again as per D:04:01-03. Check the trans fluid as per G:04:02. Don't forget to also check the final drive fluid level as it is a separate compartment unlike the 5-speed.(G:05:01) David Teitelbaum vin 10757 --- In dmcnews@xxxx, Soma576@xxxx wrote: > Hey all, > > my D's been running quite nicely lately, but there's just one little thing > that could be better, performance-wise. here's the symptoms: >
