I have just got this truck but it has been in my fianceÆs family since birth. It has about 320K mile on a factory automatic trans, that seems pretty good to me. I have been using this as my Daily Driver for the past few weeks, and noticed a strange behavior in the trans.
1) It sometimes seems like it clunks into gear, or something that feels like being rearended (I keep looking back and nobody is even close), when coming to a stop or leaving a stop right before you get on the throttle.
2)It sometimes starts out in second gear no matter how hard or soft you get on the throttle, while towing my car, I sometime had to manually put it in Low to get moving, because it started in second.

Are these known problems? I did a search and didnÆt come up with too much on both of these issues. I did se a lot of recommendations to swap in a Manual trans. Are there any write up on what is takes to do that swap? I donÆt have the money right now and the trans still operates, I am just wondering about the future.
