tranny slipping? 4L60E

tranny slipping? 4L60E

Postby JonnyDelux [OP] » July 1st 2017, 7:44pm

when travelling between 55-65, I can feel when the gear change from 3 to 4 in a big, lurching way, but only when it's going up in gear, not down. Also, the other day, I was driving around 15mph up a really steep hill, maintaining 15mph but slowly accelerating because of the steep grade, the van was repeatedly lurching forward every other second. Is that the transmission slipping? Sometimes it's a little slugglish accelerating in 1st gear, but I only notice that sometimes.

sounds more like injection or ignition issues.

AutomaticThe purpose of an Automatic Transmission is similar to that of a manual transmission, the auto tranny's primary duty is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds.
