Hi Rooster2
Perhaps I should have been clearer in my post. The beginning of this user's post is my exact problem also....Although he claims he didn't have any delayed engagement from P - D. I had a 3-4 second delay in N, R, or P to D, but I also had the above problem occasionally...it would feel like it would slip out of D at a red light or stop sign, then when you hit the gas it would engage in D kind of hard... It didn't happen very often, but just enough to be worried about.
Since I added the Trans-X the delayed engagement to D is down to 1-2 seconds and I haven't had a slippage out of D and a red light....but I don't know if that is just coincidence because it didn't happen that often to begin with. I don't drive the car a lot (over the last year of ownership about 7K miles) so I guess only time will tell if Trans-X fixed that also.
Thanks
