Transmission slipping

My trans goes fine in 1st. And 2 ND but 3rd. Gear slips
When an automatic transmission will shift up to second, but won't work beyond that, it might caused by a low fluid level. This can cause slipping and shift problems, and should be the first thing you check. If fluid is at the proper level and clean, check linkage, especially if the vehicle is older, like yours, or high on miles. Linkage can wear out and cables can stretch. Next, the problem could be electrical. Might be as simple as a bad speed sensor or a PCM problem. Next, and this might seem somewhat remote, but if you lose a catalytic converter heat shield, that could cause overheating and transmission internal wear.
Sounds like it’s already too late, but you can try a transmission service and add a quart of TrasnX to the fluid and carefully drive it around for about 30 minutes then park it and let it sit for a few days, then try normal driving, if it helped then service the transmission again and add another quart of TransX and hope for the best. If it didn’t help then the transmission needs overhauled or repalced. .
I like Gene's answer... Or is it GA... OK, which is it?
