I recently put a low milage 93 toyota engine into a 90 toyota. The trans match for the year difference, but ever since then fifth gear keeps poping out while im diving. What do you think the problem is? is the new engine just coinsidence?

Well, it could be any number of things, but I generally look for the simplest and easiest explanation when I am diagnosing a problem on a car. If the trans was working fine before the engine swap, then I would guess that your linkage is simply not adjusted properly so taht when you shift it into gear it is never really all the way in.

You took a tired old engine and transmission out and put a new(er) engine on the same tired old transmission. When you properly maintained an engine and transmission wear out at the same rate; some times the transmission goes before the engine though.
Sounds like there was a problem with the transmission before the engine swap that didnt show its self till the new engine went in. Or the new engine just push the transmissionn over the edge.
Take it to a good and I mean good transmission shop. See if they can give it a good rebuild and you should be fine.
Just a little tip for next time.
If you have a high milage engine with a high milage transmission and you swap the engine out. While you have everything apart give some attention to the trany change the oil, give it a shift kit, or overhaul. It work just as hard as that resently retired engine.

the transmission was probably weak to start with, adding extra power just exaggerated the problem. I could be that the syncro gears are worn or the shifting forks or engagement gears called "dogs" that have special ears on them to engage the other gears have worn down so they are rounded instead of sharp, then the gear just slides off the other instead of taking the torque. Time to rebuild or just (like my friend did in his 65 Chevrolet pickup with a bored-out engine and loads of more power) used a bungee cord to hold the stick shift in the gear that slipped. It looked okie and sloppy but the thing worked and the tranny held. You had to hold onto the dash because sometimes the door would fly open around hard cornering. My advice is to find a good used one at a wrecking yard with a guarantee or try a re-man w/ a guarantee. Make sure you are given a warranty of at least a year. either way you got to do something about it or you may need to power on just to find a false neutral or worse.

If it wasn't doing it before I would check all the motor and tranny mounts to make sure they are correct and properly installed for 90 model/sounds like geometry is not right causing bind in shifting linkages
