Transmission fluid question

[MattMacMan]

Buddy, this is gold! Thanks so much for your willingness to help. Fortunately after digging in the web I found the procedure and actually have done it twice!
But with no luck. The bang at low speed is not always but everyday. I tested it manually and discovered a slight delay from 2nd to 3rd and that shift is quite harsh compared to all others. At this point I'm inclined to replace the solenoid pack. I'm just still asking if it makes sense. what say you? BTW I could use a step by step Tech Guide if you happen to find one.

Let me see if I can pull the guide up for ya. And yeah man, no worries! We Service Advisors arent all sleezy lol. Some of us DO care. Ill report back.
