Hey,
OKAY, So i have been dealing with a hard shifting issue for months now, Pretty much a hard 1-2 shift and hard 2-3 shift, It would rev high to like 3000-4000 then drop into the next gear. It would go away if i restarted the car, here's the original thread for that if you want to get up to speed

So i took it to a transmission shop, They said said a worn valve in the valvebody caused pressure issues hence why it shifted weird, And this also caused premature wear on the clutch. So i paid $3500 for a full rebuild, After just 1 day of getting the car back, the issue was back, just like before. So i took it back, So they are still trying to "figure" it out, but one answer they had was that maybe a faulty fuel relay was to blame? now im no trained mechanic, but in my experience with faulty fuel relays, Symptoms were more like stalling, and having a hard time starting. Never heard of one causing shifting issues... Im worried they are going to chalk this up to a "fuel" issue and send me on my way. Any help from you guys would be great.
