Re: RPMs increase but power doesn't
To be honest, it sounds like the tranny is worn out. You mentioned that the tranny leaks. Before you try your hard power accelerating, are you making sure that the tranny fluid is where it's supposed to be? Low fluid levels will make for a slipping tranny. If the fluid levels are correct and you still get the slipping, then it more than likely indicates a tranny where the clutch packs are worn to the point of needing a rebuild. I was close to this point. My original 67 Powerglide would leave hard and pull, but shifting from low to high it would take some time. I went to the next level and ditched the PG and went to a TKO 600. I run 4.10's and wanted to be able to drive the car on the highway. The reason for going to the manual is I was bored of just puting it in gear and going. It sounds like it's time for either a new tranny or to rebuild this one. Find yourself a GOOD tranny shop. They have gauges they can hook to the input and output ports of the tranny and gauge what condition the tranny is in. Hope this helps.
