that was my problem before.

try to replace atf and filter first........
if problem persists, you have to change the clutch of the a/t.
parang mga plates lang yun........usually this is the remedy kung sa 3rd or 4th gear ang hirap pumasok. delikado kung 1st and second. internal clutch na ang may tama nun.

kung may shift shock naman.........damay mo na rin ang valve body.

hindi na kailangan ibaba yung tranny mo dun...........yun yung tinatawag nilang dukot.

me i just had my transmission replaced.......bang for the pocket talaga.
