Of course... just thought I would mention it. In fact with dropping the pan you have done more than most.

I am guessing you are using the FS5A-EL (5-speed ATX) JATCO transmission. I have the same trans in my 2004 and it uses 3ed gear for everything. It seems to have a pathologic aversion to 2nd and will use 3rd all the way down to 6mph.

You may have worn out bands and your senses are telling you so before the computer has triggered its input/output RPM ratios to indicate as much.

I am pretty sure rebuilds are out of reach for most peoples sense of cost/benefit but you may be able to pick up a used one for relatively cheap.

If you are inclined mechanically here is a list of possible faults.

I may even have the Workshop manual on my work computer if you want to dive deep.
