I know that there are a ton of threads on this transmission and I have read through a bunch of them to see if any related to my problem but, could not find any.
Anyway, my transmission will not go into drive when it sits and idles for any length of time. I have to rev it up to get it to drop into gear and then it shifts fine as long as I leave it in drive. If I stop and put into park and let it idle (for even a minute) it will not go into gear. I have to sit there and rev the crap out of it to get into gear. BTW I get alot of strange looks when I do that also.
Reverse is fine. The fluid level is fine. The fluid also does not smell burned either.
I want to change the transmission fluid and filter but not sure if I will be wasting that money or not if it is a bigger issue.
