I was driving on the freeway and at 60mph the van was not shifting into the next gear. I took my foot off the gas and the transmission suddenly did something wierd and it sounded like the engine was revving up very fast but the van was not going forward. I pulled over and shut it off. Upon restart I could proceed only a short distance and the same thing occured. Now I also realize I cannot go in reverse. The van drives forward only in first gear. Any ideas?

I have a 1998 blzer S10 with a 4.1L V6. i just bought it a few weeks a go. it has been running fine. then the lifters started tapping all of a sudden. it sounded like it was from the back of the engine. when i pulled the valve cover on the right side and started the engin the frount push rod shot oil alll the way to the fender. the rest of the push rods had almost no oil coming from them and the back one had no oil. my question is do i have a lifter problem or do i have more trouble??????? the oil PSI runs about 40 when driving and about 20 at idle. the oil is relativly new les that a 1000 miles.
