Update on azkid's 1988 Burb

[arizona kid]

Well drained the tranny and replaced the filter on my 1988 Burb hoping to get the thing out of first gear (th700r4). I had no probs with pan and fluid yet didnt fix the no-shift-into-2nd problem. So , I adjusted the TV cable from highest (towards firewall) to about where it was originally set when I bought it 8 days ago. I still feel there is a slight adjustment problem.......?? Or possiblly the valves are clogged from 4 wheeling here in dirty azz Arizona So I may possibly use some detergent in new tranny fluid...what y'al think ?? Kevin
