The A4LD on my 88 ranger 2wd is acting odd. It won’t shift into second unless I let off the throttle. However, here’s the odd part. When the truck is cold, it shifts fine. It’s until it warms up a little ways down the road it stops shifting on its own. Once you let off and it goes to second all the other gears are perfect. Every now and then it’ll shift correctly on its own, normally when going up a hill which I found odd. You can wind the truck out to 4 or around 5,000rpm and it’ll shift into second that way, I just don’t like to do that. It doesn’t slip either. So I figured classic stuck governor. So I changed it with the upgraded weight and cleaned it. Although, it wasn’t stuck, it did have some resistance to it. I also changed the o rings on the reverse servo as they were leaking. Well after doing this I still have the same shifting issue. You have to let off to get it to shift when warm. I’ve adjusted the tv cable but that didn’t fix my issue either. I also replaced the modulator a while back with a factory replacement after having too much trouble with aftermarket replacements. Could it be a Possible leaking valve body gasket or a stuck valve? I’ve heard of others having similar problems and it being the valve body to blame. I wondered if my external cooler is clogged causing the fluid to get too hot? Not sure if this would happen, just an idea. It’s the small factory unit. I’ve got a much larger one I plan to use just haven’t installed yet. I just figured I’d see what you guys had to say to possibly give me some advice as to what to do.
