This summer I was on a 900 mile road trip down to Colorado for work when my 2003 AWD pilot started experiencing transmission issues at roughly 170,000 miles. Third gear seemed to be completely dropped and it would rev high RPMs before slamming into high gear, not long after I got the blinking "D" light and a check engine light with code P0730 "incorrect gear ratio". I got the car to the only mechanic in Moab that was willing to look at a Honda. He suggested flushing the trans to see if that makes a difference. $250 later, the problem was still occurring. I also tried checking all the external solenoids, which were full of metal shavings but were fully functioning. I then made the decision to try to make it to the nearest dealership (100 miles away). After limping the car down the highway in low gear, the dealership told me that the transmission is shot, most likely a blown gear box or damaged friction plates. I ended up getting towed half-way across the country to get home. Since then I have been considering options for a repair however the car is essentially totaled. The dealership quoted me around $4,000 for a rebuilt trans and other shops quoted around $3,000. I made the decision to order a rebuilt transmission and attempt the swap myself (still very expensive). This will also mean replacing the torque converter and adding a trans cooler on the radiator. I have basic mechanical knowledge and have been told its a doable repair with enough time investment. Unfortunately there doesn't seem to be any straightforward instructional videos or manuals on a transmission swap. I understand that this is a large repair and there are ALOT of parts to keep straight. Has anyone ever performed this repair on their own? Any advice on steps to take while removing the core? I have a shop full of tools and a couple friends with pretty good mechanical knowledge. Any advice helps!
