Default Cant decide if truck wants to shift into overdrive or not - 10-12-2004 , 12:33 AM






When I am driving I approach a hill and with steady pressure on the gas
pedal when I start to rise up the hill my truck feels like it is trying to
kick into overdrive and then decides that it does not want to and kicks
back out. It only does this when I am going up a hill. I just bought the
truck and I think the guy put a shift kit in it because that is what it
feels like. I did not know if this was the problem or what but it is
really annoying. I was wondering if anyone out there has ever had this
problem or know what it might be. It also doesnt do it all of the time
just whenever it wants to I guess. Thanks for any help anyone can give me.

Chevy automatics can never decide what gear to be in. Stomp on your gas
really hard, it will drop down about 7 gears too many, pop back up, and go
from there....

Thanks gremlin I tried that and it didnt work. I have talked to a few
people and they have said it could be one of two things. 1. It could be a
transmission sensor or 2. It could be that the transmission needs to be
flushed out because maybe all of the junk in the transmission could be
flushed around due to when I was trying to pull someone out of the mud.
The guy who told me this said that possibly all the junk in the
transmission was just broke loose when I was trying to pull my friend out
of the mud. Possibility? I dont know for sure.

Your buddy needs a lesson in transmission internals. Your transmission has
a filter which prevents material from being sucked out of the pan in the oil
feed circuit. If your tranny was full of "junk" the worst that could happen
would be a plugged filter and your tranny wouldn't work at all, not just
have trouble in OD.

I need to know the year, model and mileage of your truck. Assuming you have
a 4-speed transmission, are you sure you're not just feeling and hearing the
torque convertor unlocking and locking?

Hey Doc;

EVERYBODY has a cousin / uncle / buddy / guy he went to school with / friend
who works in a dealership-repair shop-parts store / pal who read all about
it on the internet .............all of whom knows EXACTLY what the problem
is

Transurgeons's First Law: Not knowing the year / miles / engine makes it
pretty damned hard to even form an opinion
Transurgeons Second Law : Without a scan for codes / pressure test / road
test it's anyone's guess what the problem is
Transurgeon's Third Law: There is NOTHING worse than a customer entering
the shop clutching a wad of printer paper.........

Ok here is some more iformation on the truck. It is a 96 Chevrolet k1500
4x4 with about 112,000 miles on it. Sorry for not saying that befor but it
just kinda slipped my mind. The main thing I am concerned about is what
is it and did I do it when I was trying to pull my friend out. I have
talked to a couple different people and everyone is telling different
thing. torque converter, Trans sensor, need transmision flush, Bad
transmission and so on. Who knows??? I sure dont. Thanks for any
suggestions.

Ah yes, the ever-present know-it-all. He or she knows EXACTLY what's wrong,
but hasn't a clue how to fix it!
