Transmissions Ford Ranger

transmission problem in a 1994 ford Ranger?

About three years ago I had a leak fixed (transmission seal) on my Ford Ranger five speed transmission. I had the work done during the summer, and had no problems until winter came. When the temperature outside is below about 45 degrees, the transmission will not go into any gear until the truck warms up completely to its normal operating temperature. It works fine once it is warmed up. The shop that did the work is out of business. I have a theory that they put the wrong weight transmission fluid in when they fixed the seal. Is this possible?
I should add that this a manual transmission, 5 speed overdrive, and Ive had no problems with it other than the refusing to go into gear when cold.

This is possible. The early Fords used a type F fluid. It is thicker then the new stuff, Dex tron 3.
Thy stopped using type F a while back but you can still find it for the older Fords. If thy did put it in, yes it will make the trans not work till it gets hot.
About the only thing you can do is get it flushed and have a trans shop put in Dex ton 3
