There are DIY tutorials out there. Not a difficult project, with your abilities you'll not have trouble doing it. Top tip - remove the side entry port before draining all your fluid and then finding out you can't open the fill port.

However, I'm not holding out positive results for you. You're headed down the same path I took. Changed the trans fluid and it didn't help. I had a 3-2 downshift crunch, but basically the same issue as a 1-2 upshift - 2nd gear synchro issue.

I shipped my trans off to AZ for a $2K repair - $1300 for parts and $600 labor. Then a pic arrived of the ring & pinion with a chunk missing from a tooth. Add another $2K. Then an examination of the 3 & 4 synchros added another $2K. Now I'm w/in a $1K of a $7K reman. Cha-ching, cha-ching, cha-ching.

Hope you have better luck.
