MCM Realtor Posted September 21, 2008 Share Posted September 21, 2008 I have a '63 Riviera and the transmission is not going into reverse any more. Does anyone know of a repair shop in the Dallas TX area that they recommend? Does it sound like I need a rebuild of the transmission? It shifts fine when driving, it has been leaking some transmission fuild and now it will not go in reverse. Thanks.

Jim Cannon Posted September 21, 2008 Share Posted September 21, 2008 Sounds like an internal seal leak. Did you check fluid level? If fluid level is correct (check while engine is running, in Park) then yes it sounds like transmission needs a rebuild.I don't know if a rebuilder in the area but I know others on the list do.

tim63riv Posted September 21, 2008 Share Posted September 21, 2008 Ed,What probably happened is that the reverse band servo strut fell out. This happens as the reverse band wears and is not periodically adjusted. I'm not sure that this strut can be repositioned correctly without disassembly of the transmission. Probably a good time to freshen up the Dynaflow anyway!Tim Link to comment Share on other sites More sharing options...

tim63riv Posted September 30, 2008 Share Posted September 30, 2008 Jim,5-65 and 5-66 in the 1963 Chassis service manual. I don't see a maintenance interval listed, but that was something that was done back in the day. I also have a Motor's manual from 1963 that details the procedure, but again, not the interval. Might be because it is only able to be done by "feel" when the transmission is in the car. The information on the strut falling out came from Tom Telesco, a very reliable source. I'll be going through a 63 Dynaflow in the coming weeks as my Black car seems to have developed a pump to converter seal leak that is pretty bad. I'll keep in touch!Thanks,Tim Link to comment Share on other sites More sharing options...

I've never done it on my car and thought I should. But then I could not find the procedure. I'll dig into the books tonight where you directed me.
