1998 Yukon High Revving?

[Koby]

In my 1998 Yukon, I am finding that I need to press the gas pedal a lot more in order to go anywhere. It's like the engine isn't making enough power to accelerate normally. Now this truck has been sitting a while, and I'm sure it needs a tune-up badly anyway, I'm just wanting to make sure the engine is at fault and not the transmission. My dad said the trans may be slipping or something. I just want to know what the problem is and what options I have available.

Thanks

Most likely the transmission. Check your fluid on the dipstick. Is it pink or brownish? Does it smell burnt? If its brownish and smells burnt then you have clutches slipping and your transmission is about to die soon.

It's still pink and I can't smell anything, but ive read online that a simple filter change can fix some of the small transmission problems. But I'd say that the transmission is doing great for being at 266k miles, and probably hasn't had any transmission work done since 100-150k. The last owner didnt care about it at all.
