Transmission?

[bradss_03]

I have an 03 Silverado SS and lately when i go to take off, it doesnt have the power it should when taking off. Also when I am getting up to speed it doesnt seem like the truck is shifting into the next higher gear because the RPMs continue to stay high. Anyone experienced this problem???? Thanks!

Sounds like your transmission is on its way out. Probably needs a rebuild how many miles are on it?

It just turned 90k. I know its in need of a transmission service which I was actually going to have done tomorrow.

This is exactly what mine is doing about 4 days after my blower install. First gear climbs to about 3-3500 rpm before it shifts. But its more like slipping into second gear and is very hesitant. Does the same thing when shifting into 3rd but not as bad. Ordered my Performabuilt on Monday, should have it next week.

It seems to have been the remote starting security system. I guess something to the effect that the truck itself was conflicting with the remote start.

Two things to mention there. The first is that it sounds as if the remote start may have blown the "ign 0" fuse which will put the trans into limp mode causing it to take off in third gear and never upshift to fourth. This of course will create a very lazy take off from a standing start as well as give you the feeling like it isn't shifting. Many remote start's are wired in using this fuse for a power source and this is a result of that. Something else that will create the same simptoms for those interested is plugged cats. Plugged catalytic converters will create a lack of power condition causing a sluggish acceleration as well as very poor shift feel, including at times no upshift to 4th, no tcc, or very delayed shifts.
