For a few weeks now I have noticed that my truck seems to shake/vibrate when trying to downshift into 1st coming to a stop or slowing down to lower than 25ish mph. When I first noticed it, it only did when the truck was cold. Now it seems to be more often and doesn't matter if the truck is warm or not. I thought it may be the breaks but I have taken my foot off the breaks and coasted and the truck continues to shake. It doesn't feel like an engine issue, but what do I know. The truck has roughly 27k miles and is a 4x2 2.7. Before I go do anything, has anyone else experienced this?
Thanks in advance!
