I have a 88 4-runner 3.0 with a A340H auto tranny. First tranny lost all forward gears but had reverse. I thought it was blown, bought a new tranny from a working vehicle same tranny and everything. Second tranny, put it in worked great for about 10 minutes that i test drove it. I turned the engine off and started it with no forward gears only reverse again, the computers have been changed, cooler lines have been blown out with air, changed the fluids several times have have tried different amounts of fluid and still nothing......anybody have any ideas....PLEASE HELP!!!! I dont want to pull the tranny and have to rebuilt it when thats not the case!!!!!
