gcosse05 Posted July 1, 2013 Report Share Posted July 1, 2013 Hey guys I got a 2003 SSS. LT headers, intake, cat delete, dual flowmasters, and a Zippy tune. My question is, when I first got the truck (before mods) I noticed that when I stick it to the floor from say...35-55 mph, it seems to only downshift once instead of hitting say 2nd or 1st like I remember my previous Vmaxx doing. I thought it was because previous owner had it on 24's. After the recent mods listed above, and now on 20's, its a little better, but not Like I remember. Is this a tune issue? It shifts and drives fine, just would like for it to downshift for me when I'm doin 40mph and a cobalt rolls up on me and I stick it to the floor and it goes to 3rd and the cobalt leaves me lol. I did a complete service on the truck when I got it and the tranny fluid was/is not as pinkish red as id like but doesn't smell horrible so I decided go leave it alone. Help me out here. Thanks in advance Quote Link to comment Share on other sites More sharing options...
Blazerdave2000 Posted July 1, 2013 Report Share Posted July 1, 2013 Not a expert what so ever. But sounds like that's in the tune. Mine did that but it was fixed in the tune by zippy. Mine could of been due to having a stall converter and he tuned it for that maybe. Not sure. Good luck bro Quote Link to comment Share on other sites More sharing options...
gcosse05 Posted July 1, 2013 Author Report Share Posted July 1, 2013 Thanks for the info. I guess ill start by contacting zippy Quote Link to comment Share on other sites More sharing options...
Blazerdave2000 Posted July 2, 2013 Report Share Posted July 2, 2013 Yeah I'd just ask and see what he says. He was always helpful with my questions. Quote Link to comment Share on other sites More sharing options...
tburkdoll Posted July 2, 2013 Report Share Posted July 2, 2013 I bet the 4.10 gear ratio is the difference. Your v max im sure had 3.73 gears... higher gear allowed it to shift on down to first at that speed Quote Link to comment Share on other sites More sharing options...
cb2big4u Posted July 2, 2013 Report Share Posted July 2, 2013 (edited) 35-40 is a shitty drop point for 4.10 gears. 30 mph hits first and 35-40 hits second but on the extremely low end. A higher than factory stall will help that a little.

SSenvy Posted July 2, 2013 Report Share Posted July 2, 2013 ^^ what he said These trucks are dogs when kicked down around 35-40'ish. Like mentioned slow to 20-30, or 45-60 Quote Link to comment Share on other sites More sharing options...
gcosse05 Posted July 2, 2013 Author Report Share Posted July 2, 2013 Well that makes sense. I can't wait to finish my parts list so I can break that transmission and get a built one lmao. I put the mods I have listed in my origional post on it within the first 7 days of ownership. Heads, cam, FAST102mm intake and tb, stall coming next month! Thanks for the info huys. I thought something may have been wrong. I knew I could ask you guys tho! Quote Link to comment Share on other sites More sharing options...
