Hello all,
I don't know how better to describe this, but it's getting to be quite the annoyance. I pulled my '99 Corvette home 120mi, and while it was smooth sailing for the most part, I'm left pondering this issue - I'm hoping someone may have input that could lead me in the right direction.
Initial acceleration from a stop in 2wd feels sloppy...like the driveshaft is flopping around or something isn't grabbing. I couldn't break the tires loose if I tried (I'm not trying, but my point is I don't get full power from a standstill), so I've been under the impression it was some sort of torque management to save the transmission.
During the drive home a tractor pulled in front of me so I slowed to about 3-5mph. I couldn't safely pass until we reached one of the biggest/steepest hills on my journey (a 1/2mi pull). With a line of cars behind me waiting I put it in 1st and pinned the throttle. On an uphill with that weight behind me acceleration was 'sloppy' until I hit about 20mph...my wife asked if everything was okay and I nervously said, "yeah, it always does this when I first get into it, it'll smooth out in a sec."
Is this normal? Driving around empty that feeling is less-pronounced, and I haven't noticed torque converter shuddering. I used Lubrigard when I thought it could be the issue, and nothing changed. I drained and refilled ATF (and changed filter) 10k miles ago - fluid was prestine without burning odor, changed rear-end oil at the same time, engine oil is fresh 10w30, new shocks all around last year, two months ago I pulled the bed off and cleaned up the frame, rust-bullet the whole thing, put in new fuel pump and tank, cleaned/fixed all grounds I could find, and while the truck feels stronger (and no longer leaks anything), I'm still getting that slack-feeling.
The truck rockets away smoothly from a stop in 4wd...also confusing to me. One of my friends suggested a bad u-joint, but last year my mechanic said, "they all seem tight, it's an old truck, just drive it." He greased everything he could and on I went. I still wonder about that...additionally there's a vibration felt in the whole truck between 30-50mph, getting wheels/tires balanced didn't fix that so I've just lived with it.
Sorry for the book, looking forward to any and all input. I appreciate you guys!
