I'm inclined to agree with Bill. Aside from finding a shop that actually listens to you, you need to find a transmission rebuilder that understands transmissions....all of them (new and old). There are alot of so called 'technicians' these days that have been taught how to disassemble and then reassemble mechanical devices like transmissions, over and over and over. Problem is, very few actually understand what it is they're working on and how it functions. I'm often shocked at the level of understanding some of the younger mechanics actually have.....never mind service managers. I'm not an expert on fluids but your transmission guy should be, sounds like he's crossing his fingers as you drive away.

Not only did he not do what you wanted, but he has had to go into the transmission a number of times. Worth the shipping to move it to a competent builder who is familiar with not only the older Torqueflites, but with the 300 specs. I am sure that Chrysler does not recommend Dextron at all. I am not convinced that even the latest Chrysler ATF-4 has the proper friction co-efficient for our older transmissions, no matter what Chrysler says. http://www.wd-wpp.com/specsheet/atfspec.pdf Bill Huff At 5/14/201201:15 PM, Mark Lindahl wrote: > > >Hi All, > >I had my '63 torqueflight rebuilt last year, but it needed to be >readjusted/rebuilt again since the car moved forward (slight creep) when the >engine was revved in neutral. > >I think they did not pay attention to the gap need in the clutches.
