Hi I'm new to the forum but I figured I would post to maybe get some insight or helpful tips. I have a 93 chevrolet blazer 2 door full size 4x4 with 180k miles that I just bought a month ago. When I bought it the guy said he replaced the tranny with one from a 93 suburban so I figured it was good. The other day as I'm driving down the highway I get off the exit to get gas and at the red light as I go to accelerate, my engine just revs and I've lost all gears including reverse. I try to fix anything if I can before I go to a mechanic so I've replaced the whole transmission solenoid kit because I thought that may be the problem but turns out it wasn't. I've also took off the differential cover and checked my gears back there and they were fine. Now I think it's maybe my transfer case or torque converter. I'm puzzled at the moment and thought someone could maybe help me out to what it may be. Thanks.
