Hi Nina,
I live in san diego too and have a 1985 toyota dolphin that needs its automatic transmission removed and replaced. First off, did you ever find a place to do your tranny work? Were they affordable/how mmuch did they charge you to replace or rebuild yours? Also, where did you or the shop find the new/used or rebuilt tranny that they used to install in your motorhome. Im really in need of some info and was hoping you had gotten some goods leads and had some info and advice for me, especially since we live in the same vicinity! Let me know, Thanks!
