transmission spring

It did bring up something I have not heard about though. It mentions a spring in the valve body that is not present on a car equipped with a 2x4. Anyone aware of this and what it does? I am going to be rebuilding the transmission soon in my 60 plymouth and I am planning a 2x4 (maybe not right away but not to far into its road going future) and wonder if I should remove this spring or not. Whats the thoughts on this https://www.google.com/search?q=1960+torqueflite+rebuild&rlz=1C1CHBF...

The accumulator absorbs the shock created by rapid fluid movement both on the 1-2 up-shift and on the initial shift to Drive. There is a belief that the presence of the spring "softens" the 1-2 up-shift but it doesn't and the belief is that removing the spring "firms" the 1-2 up-shift...again, it doesn't. The absence of the spring puts extra strain on the rear clutch so I have no idea why the factory left it out on performance installations all the way up into the seventies. ttotired Posted 2023-04-24 5:50 PM (#629111 - in reply to #629097) Subject: Re: transmission spring Expert 5K+ Posts: 8445 Location: Perth Australia Thankyou
