1989 S10 transmission not shifting [SOLVED]

I have a 1989 s10 automatic transmission. When I drive, it it pulls great the first change – no problem. But the second does not engage. Will Sea Foam Trans Tune solve this problem?

When shifting simply doesn’t happen, there are 2 very common problems: fluid quality and fluid level. Automatic transmission fluid should be bright red or red in color. Check your fluid level and condition. If both are good, Trans Tune may not help you. Not shifting may simply be a failed transmission component as well. I’d recommend having the vehicle inspected by a reputable repair facility in your area prior to adding Sea Foam Trans Tune.
