Thanks Pete! It won't shift into fourth at all. It sometimes shifts normally from one, two, and then third and won't hit fourth. Sometimes it gets stuck in first and I shift to N then to OD and it's in second. Also sometimes I take off slowly and it waits till 2500 RPM to shift into second, snapping my neck a little.
I was hoping I could fix this without pulling the trans. so am trying to find out what the problem is.

There is an additive that will make the fluid more slippery. This helps to unbind the valves and sleeves that can cause this problem. I know my description is vague but shortly after overhaul my A4 started doing the same thing. The shop added this product and the problem stopped immediately and has never returned.
Goto a NAPA store and ask for the transmission addititive. Comes in a black or red bottle. No kidding, its synthetic sperm whale oil. I'm sure someone will chime in with the product name soon enough.

Sometimes trash(worn clutch material and other debris) gets caught up in the valve body passages, hanging up valves. I would pick up a new seperator plate from the dealer, an upper and lower valve body gaskets, 3 cans of carb cleaner, filter and pan gasket and 5 qts of fluid. Drop the pan, drop the valve body, completely disassemble it, spit shine the valves and passages and reassemble. All labor, not much in parts.

I tried the Seafoam trans. flush and changing the fluid but there is no change. I'm going to drop the pan this weekend, I have all those parts ready. What should I look for if the 3/4 pack is damaged?
Right now there is no fourth gear. When the engine is not under load the RPM drops like the trans. is in N.

My Fluid looks OK .
I didn't have a problem going into 4 th untill I changed my engine (bigger).
The car was down for about 2 months.
After the new engine install, it would have delayed shifting in all gears. But, When it warmed up it would shift fine. Now after about 1000 miles, it will not go into forth.
1-3 work fine but are still delayed untill hot?
When I say delayed, I mean excessive RPM required befor shifting.

When I say delayed, I mean excessive RPM required before shifting.

After driving the car some more with the flush, fourth gear came back.
