4T60E shift problem

Hello all...new to this forum.

We have a 94 Park Avenue that won't shift into 3rd gear during in town driving or if in overdrive on the highway it won't shift back to overdrive if passing someone. Has anyone seen this problem with the auto tranny?

TIA,

yes, You need a rebiuld.. The tranny is shot at this point. get it replaced and install a aftermarket tranny cooler. You'll be glad you did!
