Got my 4.10's in ya their great. Now I have no traction but when I leave it in drive instead of manual shifting it just takes forever to shift it peaks out in first and stays there for about a second and then it shifts. If I do it manualy its fine. Is this normal?

It will go away in about a month because I am getting my shift points redone ,but Im just curious if this is normal.

You losers and your electronic shiftpoints [8D]

Seriously though I have no idea, I threw a set of 3.90's in my AOD and dont have any problems... shifts right on point.

Yes, it's perfectly normal. In first gear ifI floored it, I'd actually bounce off the rev limiter for a sec before it shifted. When i got my Tweecer, I readjusted my shift points to fix the problem. Steeper gears throws shift points out of whack.

ok good I guess it just an excuse to get a tune sooner

Are you tuning it yourself or having someone else do it? Remember that with the slight delay in shift time, you actually program the shift points at WOT to be earlier than you want. You want to program teh RPM for te 1-2 shift to be about 1000 RPM early, and you want 2-3 to be about 500 RPM early to account for the delay. These are approximate, but they're a good starting point.

For example if you want it to shift from 1 to 2 at 5200 RPM, set it at 4200 RPM. if you want the same for the 2-3 shift, set it at 4700. Those are decent starting points.

If someone else is tuning it for you, then don't worry about it. They'll fix it

One more recommendation... do a dyno pull in each gear so you know exactly when you peak. If you shift too early, it takes longer to get in your powerband on your next hear and you're missing some good pulling power in your current gear. if you shift too late, you're just wasting tprecious seconds. Once you see where you peak in each gear, then you know exactly when you want the car to shift for you when it's time to program th shift points.

How much did they wake up the car? what rpm's are you at going 60 and 70?

Ive got 4.10's and an AOD and the rpm's are only up 500 from the stock 2.73's.

i hope your not beating you car after getting your rear end work done...new bearings like thatdont like heat.

I'm not I'm waiting 100 miles at 45 than another 100 on the highway.
And whoever said what rpms am I at I dont know and I dont care but I like it
