RPM revs high when car shifts

[Chandler1122]

I have a 2001 Honda Accord LX Automatic with 53000 miles on it. It also burns oil i guess because there is no oil stains anywhere i go and i have to check the oil once every other week to make sure it is full. I've had to put at least 5qt's of oil in the engine every 6 weeks. Now onto the reving problem. When driving and the car goes to shift it will rev up about 300-600 rpms before it shifts and when it does shift it slams into gear jerking the car and making a loud noise. I took it to honda and they couldnt figure out the oil problem and told me the shifting problem was the V-TEC sensor. I had that replaced for about 500$ and it didn't do anything with shifting but boosted my gas mileage a little bit. Does anyone have an idea of what the problem could be?

Thanks, Eric

Sounds like the tranny fluid is low or tranny is going bad one or the other
