You might try adjusting your bands, there an adjuster on the side and one in the tranny. This helps with the shifting. Also check your TV cable adjustment. If moved somehow it will cause wierd shifting. Get a repair manual it shows you how to adjust everything really clearly. Thats all i can think of. Also if the truck you pulled the bigger motor from, it might of had a bigger tranny(48re) instead of 318s typical 46re. If so try reflashing the computer and see if that helps.

The bands have nothing to do with the 3-4 shift, although its never a bad idea to check the 2nd gear band adjustment.

More then likely the pcm is missing a signal that allows for the 3-4(OD) shift. Its based on speed, TPS and possibly some other inputs from the engine.

It could either be a bad TCC Lockup and Clutch solenoid or they were unplugged by accident. The main thing is there are more solenoids besides the Pressure Solenoid. There are the Torque Converter Clutch and the OD Solenoid. OD is your 4th gear.

Those solenoids will look like this: https://www.rockauto.com/info/155/ros52-0347_1__ra_p.jpg
