Hi out there.
Background my VS is a 75k km one pensioner owner really good mech. condn. but as my previous VS the 4L60E is not the smartest box on the market, this ones worth spending a little doe on.
So my question is what can be done without box out to improve the shift I'm not looking for miracles just two things:
1. A little firmer quicker shifts up and down.
2. My main bug bear is the box holding on to higher gears when going to accelerate out of an intersection it changes late and with a thump from back near the diff, centre bearing and diff all good, any suggestions ?
Options I have been told about
1. Transgo/Sonnax line pressure boost valves work if that's the case which one is better?
2. Corvette servo another option?
Cheers
