Question tranny question

if i'm waiting at a light or even just pulling away from my driveway with the car in either D or 3 it seems to shift somewhat abruptly and seems almost as if it's to soon, but all the other upshifts are smooth. it won't do this on hard acceleration. is this the infamous sol. c? tps out of spec? fluid/filter was changed 5k miles ago no leaks and it doesn't do this if i press the manual button.no other symptoms i can feel.anyone care to take a guess? thanks. dennis

Re: tranny question

Hello Dennis,

It's hard to be sure from your description but that sounds like typical US SVX behavior. The 1 to 2 shift at low to moderate throttle is annoyingly early. This can be corrected with modified shift maps. You may want to take a look at my TCUs.

Re: tranny question

thanks lan. your right it seems early and a little abrupt it's good to know that it's normal. i will probably swap it out for a 5speed if and when it dies. dennis

Re: tranny question

it's not a transmission problem..from the sounds of it...they just have crappy shift maps from the factory. A performance tcu will fix it right up.

Re: tranny question

it's a requirement for all svx's. You should disconnect the atf cooler in the radiator and use a high capacity aftermarket cooler. Preferably a plate and fin cooler mounted in the drivers fender with it's own fan and thermostatically controlled relay with an inlet vent cut in the bottom of the plastic fender liner and an outlet cut in the top of the plastic fenderliner in the wheel well (the holes can be easily cut with a razor knife and many coolers come with brackets--if not they can be easily fabricated--they also often come with hose and hose clamps.)
