Hi everyone - We're posing a question to get input for one of our new SX455.com members, Joella. Joella is at a crossroads with needing a transmission repair. She currently has a TH400 with a Gear Vendors overdrive and wants to know if anyone has replaced the TH400 with a 700r4 with mods. The other option for built in overdrive would be a 2004r built right (this bolt pattern fits, the 700r4 does not without an adapter). Any input based on real-world experiences with any of these setups would be appreciated. Thanks.
