why does the vehicle tend to lurch forward as it builds speed. on 1990 Dodge Caravan

vehicle jerks or stalls at speeds in the low range up to 65 mph then it tends to remain reasonably good. seems to have poor power all along its building rpms.

It's the transaxle...check that fluid is or has been changed. Then next....check the bands. It's a subtle transition of strange gains and losses at certain speeds...wich at first one would think "engine" but...I've discovered it's torquage from the tranny pullification. Hope this works for you. Check bands.
