Ever notice that while driving that the car hesitates or refuses to go into gear? ... but after shifting into gear the engine's RPMs will surge, but the car won't move as fast as the ..... It's slow to shift gears and accelerate in Reverse, D4,D3,2 and 1.
Keeping the overdrive on during normal driving is ok. It's like making a 3 speed transmission a 4 speed. With it being an automatic, overdrive will only engage when the car speed and engine rpms meet the conditions for it to engage. NOT driving with overdrive at high speed will make the engine work much harder, and could likely cause that pulsing and surging as you have described. It's like down shifting in a manual transmission car. Keep overdrive on, it will only when when it is supposed to, automatically.
That doesn't sound like a problem, it sounds like it's shifting out of "Overdrive" due to low RPM. That would be normal. If it's more noticeable now than in the past, that's likely just wear of the parts (that's an old transmission at this point), or need transmission fluid checked/replaced. Only someone who knows transmissions can really diagnose if there is any problem, but what you are feeling is the normal downshift out of "overdrive" into the next gear, the only question is is it more noticeable now than in the past.
my name is matthew I have a 1990 passot also,
The botton on the marked with an is for overdrive! the transmisson is eletroic and the s botton put the trasnmisson in overdrive! I that out from a transmisson shop, my e mail is email@example.com
try checking the fluid level if it is even aa half pint off it can cause shift problems, if it is low add some Lucas transmisson oil condtioner this will help it shift smoother. also look at the color of the fluid is it brownish in color? if yes then it's time to change the filter and fluid. if you take it to a shop they chagre about $150.00 but it will keep you from damaging the transmisson. the oil and filter for the transmisson should be changed every 30,000 miles on any car. Thisis oone of the most overlooked items of maintence on cars peopel simply don't know about change the filter and oil till they have to pay for a new transmisson.
well not having overdrive has nothing to do with the motor you are having transmisson trouble and the first thing you need to do is get the tranni serviced flushed new filter and put a quart of lucas tranni treatment in i have seen that stuff stop tranni slip it worked in the 1999 envoy i have right now and do not floor it any more that will send your tranni to a early grave
