My mom has a 97 4 Runner with 147k miles on clock. This is what happened
She was driving home, RPM's started to jump, check engine light came on, push on the gas, no GO! Vehicle has power, but wouldn't move. Noticed what smelled to be like something burning. Get it home, looks like something is leaking near the oil plan, by the looks and smell it appears to be oil. Checked oil level, very low (Although I didn't let the vehicle run for very long, and I know you are suppose to when checking, however I don't believe it should be that low , im talking maybe 1/4 inch on the dipstick MAYBE). Start it, will go in drive, but not reverse, not sure how fast in drive, as I just nudged it forward, put it in park and rev up the gas, sounds like a rattling/fluttering, sort of sound, hard to explain??
My first guess is the transmission is shot, but it does go in drive, but no reverse. Possibly blown tranny line, maybe what I think is oil is actually tranny fluid?? ANY and ALL advice on this matter would be much appreciated... Thanks guys!
