Hi Guys,
I would like suggestions for taming my 1-2 Low Speed, Light Throttle Shift.
You can see the details of my transmission and vehicle in my signature Blog Link.
The short of it is a 2005 5.3 L33 with Magnuson Radix Supercharger, with a 4L60E converted to a 4L65E with a Sonnax Performance Pack and Circle-D Stock Stall Converter.
I have been through money pit hardware attempts to correct this. Sonnax believes its a Slide Bump, The Trans Shop guys don't have much to say on that thinking its a plain old too firm shift. Long story. Both have been very supportive but I am out of funds to do tear down and try experimentation's.
So............... not being an experienced or seasoned Tuner especially in the Trans department, I would like to try some tweaks if there are any that do not threaten the rest of the system.
What I have is a light throttle crack position from a dead stop from 0- to 2500 or so RPM back slapper from 1st to 2nd gear. Any heavier on the throttle position and the shift gets more acceptable.
I know too low on pressures and too much shift time cause wear issues but at such a low load can we calm this down with out fear?
What would you do in my situation?
Thanks.
