I have a 08 Evo with just under 12k miles on it. After sitting all night and when I am on the highway driving it and give it gas to try to accelerate quickly [usually around 3.2k RPMs the RPMs will jump up about 1200 and then just as quickly they will drop down to around they were when I first gave it gas and then climb up as normal.
Then, if I give it gas again, the RPMs will jump again but not as much as the first time. The more that I do it, the less the RPMs jump.
Any ideas on what could be causing this?
The dealer wants to drop the trans to inspect it but if it is found to be just a worn disc I will need to come up with $180 for the disassembly to cover the tech's time. If it turns out to be a worn disc, I wouldn't want to pay the dealer labor rates for install of a new clutch.
What are the chances that it is just the disc that is worn?
My theory is that there is a seal leaking oil onto the clutch disc causing it to slip. That would explain why is gets better rather than worse the more I drive it: Because the oil gets worn off and allows the clutch to grab better.
Thanks!
