Default Downshift question

My 1990 will not do a 2-1 downshift in D4 between 25-35 MPH...but it will downshift in D3...Is this normal, or is there something wrong with my transmission?
Thanks

You're ok........ I manually shift mine all the time (as in ALWAYS) and going down to 1st at more that 25 isn't a real comfortable thing....... it likes to slide the rear tires a little when I do that....... I USUALLY get to 25 or less to go for 1st.............. :seeya

vettmech is right! Downshifting to first from over 25 mph for me is :eek: ! I personally feel most comfortable going to 1st when I'm under 20mph.

I don't really know that.

Mine won't do it in D4 until I'm practically stopped. I have my lock-up speed changed on my chip so I can leave it in D4. I rarely leave it in D3. If I'm not in D4 then that means I'm manual shifting the gears one by one.
