Here is an update :


I was able to add almost a quart more of transmission fluid when the temp was around 30c. I had similar delay issues right after that yesterday but when I started the car in the morning today, there was no delay on D or R in the beginning and it seemed to engage nicely until.. I did some shifting through gears for 10 minutes or so and eventually the delay was back.

So, should I try to add more fluid right around that time? Would something in the transmission system kick in and the delay would start after some fluid gets directed there? Does the transmission cooler immediately circulate the fluid or become active after the fluid heats up a little which may lower the fluid amount in the transmission?

Thoughts?
