Chip Posted June 6, 2014 Report Share Posted June 6, 2014 I've got a 2003 ss silverado it has 76,500 it's time for a trans fluid change just put a bigger trans cooler on it's been tuned by Wheatley don't know what he changed in trans it shifts good I tow a 1200lb bass boat every weekend is it too late to install a hd shift kit and servos I already have servos 1st and 4th and updated valvebody and shift kit I don't want it to hit hard and will it need to be retuned after servos and hd shift kit or should I just install servos and change fluid?? Any help would be great!!! Thanks Ss brothers!!!!! Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted June 6, 2014 Report Share Posted June 6, 2014 If it was me, and the trans is not showing any bad sign's; I would go for it. You will want to re-tune. I believe that the harshness of the shift can be manipulated somewhat with the tune. Quote Link to comment Share on other sites More sharing options...
Muggs Posted June 6, 2014 Report Share Posted June 6, 2014 I say go for it also, like Johnny said trans not slipping or showing signs of failure you should be fine Quote Link to comment Share on other sites More sharing options...
