I have a 1998 Chev S-10, V6, 4.3L 2x4 110K. It started very quickly. While driving on express way, other cars started passing me by. I looked down at the gauges and saw that the RPM's where in redline but truck is not going very fast. I thought it had to be something in the transmission. So after getting truck home a went thru the usual process to trying to figure out what wrong. Now I have another car so sometimes I let the truck sit for a while and drive the car. Now in light of the fact I hadn't noticed any signs of any problems before this happened (leaking fluid, slippage in shifting, nothing). My question is it possible that I don't need a new transmission?? If not what could possibly be the problem. I like my truck very much and would like to be able to get back to driving it. Somebody HELP!!!!!!!

Have you checked the transmission’s fluid level? If so was the fluid level full, a clean pinkish colour or was/is it a dark colour and have a burnt smell?
You probably haven’t had a reply to you question because it is very vague with so many possibilities as to what your trucks problem really is?
By your description it does sound like a transmission issue and if the fluid is full (clean or dirty) it usually means going inside to find the root problem.
