Last weekend my son and I bought a 2005 Tacoma 4x4. During the test drive, I noticed, when 'punching' the gas, the transmission seemed to rev high, but we did not accelerate quickly - it was like the back wheels spun - but I do not think this happened. I'd like to know if anyone is aware of transmission problems (auto) like this. I'm not sure it's a problem at this time, as my son is off at school and has the truck. I will test this again during Christmas holidays. Just inquiring to see if anyone else has felt this type of problem.
