have had gearbox serviced recently and the tacho seems to be jumping in third gear from between 3000 and 4000rpm and gearbox seems to slip a little bit then when put into overdrive slips a little bit then pulls hard(or as hard as a stock vlt does)gearbox is standard vlt auto.any ideas (i really dont want to hear the box needs rebuilding

Spend $200 and get your self an auto r33 box if your worried. Its an old auto what did the service provider say about its over all condition? fluid levels may be low Dont always trust service people (could be an apprentices first shot at it)
