Default C5 kick down problem

Hi,

I have a 1998 C5 with A/T at 23.000 miles on it. It shifts perfectly up (1-2-3-4) and down (4-3-2-1) during normal drive. However, when I kick down at 4th or 3rd gears around 1.500 rpms, it directly jumps to 2nd or 1st gears, increasing suddenly the rpm up to 4000-4500. What would be the problem. I appreciate your comments and advises. Thanks.

Turgut

That would be a pretty drastic fault, and there should be codes stored. Have you checked?

when you jump on it are you putting the peddle to the floor? Try modifying your driving. Use a quick 1/2 throttle instead of a "floor it" style. This seems to give you that 1 gear down shift and that quick acceleration without dropping into 1st. It may take some practice and restraint but I find it works rather well.

I live in Turkey and I am afraid this is a rare car for this country: I'll try to find a mechanic who would work on software.

Thanks for the tip. I'll give a try tomorrow and inform you about the result. But I am afraid there is something wrong with selecting the right speed/gear combination. This only happens on kick downs.

Agree. Sounds like your car is doing what it is supposed to do.

Thankfully, on a C5 Corvette you don't need anyone or anything to check codes.

Here is the procedure to have the car nicely list off all codes for you on the driver's information center (DIC).
