My 1980 300d trans pulls up ramps, reverse is fine, but flares and slips when it gets to the point of shifting the first time . Fluid has been changed with filter vacuum switches are good mod has been ajusted up and down with no change. Kickdown seems ok car will not shift manually either I hear there is a final drive band ajustment but I cant find where it is any Ideas? also car sat for around 4 years prior to me buying it the previous owner said it got worse and worse as time went on . I had some metal in the fluid but nothing real bad . Thanks for any help at all
