I have a 98 accord 2.3. Just like many here I was having trans problems. I nursed it for 1 1/2 years and tried every low cost band-aid in existence... fluid changes x8, clean every part accessible on the outside, seafoam, Friktion Tek (worked for 2 months), lucas, trans fluid cooler, etc... Luckily, when it finally gave up the ghost it was in my driveway.
I looked back and estimated the cost of trying to find an easy fix, the cost of towing x2 when my wife drove it and the headaches of slamming into 2nd gear at 60mph. I once drove it over 50 miles on the shoulder of the highway, exits and entrances in 2nd gear. My guess is around 600-700, this includes all the honda fluid, junk yard parts, time spent....
I just purchased a low mileage import trans for 500, 300 to get it installed (that's being done today and tomorrow). I should have just replaced the trans last year... I crew I got the trans from (Orlando, FL) told me they sell more 98-2002 transmissions than any other import trans.
It seems to me that the question isn't what's a quick fix or how long will it last, it's how soon will it die....
I'm pretty sure that at some point this import trans will begin it's downward spiral as well. I will use the time I have to properly rebuild the other one...
