I bought a 2017 Tacoma TRD Sport which has a electronic limited slip in oct of2016. I thought the truck was all right and impress me. So far I the off-road capabilities this 2wheel truck is supposed to have for The TRD edition is ok. What I am not liking is the loss of power going up a mountain road/ highway/ dirt hill and driving thru sand or mud. My truck has literally loss power for seconds of time and then come back in 5 seconds later which almost caused me to get stuck. Inclines the truck does not like anything over 15% grade. The truck will lose power as if no gas is getting thru. Has anybody else have had same situation? Question what is a TSB for the tranny?
