If egr is stuck open, it can give you a low vacuum signal. Since its removed (and blocked off), there is no problem there. Yes, you can block off one line, then check which port on the modulator works best. (does the modulator hold vacuum? If its old, the diaphram inside may have failed)If so, there is nothing you can do but replace it. Can you manually shift (& downshift?) gears?
Are you absolutely sure that you got everything in the valve body correct when you installed the shift kit? even a small piece of debris can screw it all up!!

Automatic transmission not shifting gears

post year.
if tranny slips its bad tranny. (depends on year)
if the engine misfire and has weak power that is not a tranny issues
but a engine issue., have some how knows cars tell you which is which.

if you mash the throttle and the dash RPM goes way over 3000 RPM
that is in fact a bad tranny in any gear Forward or reverse.
shaking is the engine, i guess.

do you check fluid levels on your car.
and use the operators guide for the A/T tranny levels, dont guess.
use the book it has tricky steps. read it.

good luck to you.

Hi, My name is Mike and I am currentyl having tranny problems with my 2002 Silverado 2500HD 2WD 6.0 4l80e. I bought the truck knowing it had tranny problems and the issue was once the tranny would warm up...

you sound like you know what you are doing so excuse me for thinking out loud-if it were me, I would really carefully check the cable and the pawl to see that it is adjusted properly-because it sounds like either that or possibly the harness is not connected or there is a wiring problem.

Where do i find the shift solenoid on an 05 impala ls with a 3.8? car shifts hard when stopped at light and go to take off. like its in to high of a gear and then slams and jerks into 1st. however it...

all of the shifting solenoids are in side the tranny, by the sounds of if you might be able to try a service on the tranny, new filter and fluid might help alot. try that first before spending alot of money.

Hard shift from 1st to 2nd, then 2nd to 3rd.

Dont think they changed it yet but the older chrysler units had a rod that went from the throttle linkage to the transmission (maybe a cable now)...If you lengthen the rod it will increase shift pressure and give you an earlier shift.

Transmission shifts extremely hard.I had trans rebuilt, still

The Buick (GM) Corp, has offically released this as an on-going problem with this style of tranny, but will not issue a recall. Basically, it can only be fixed by replacing the pressure valve within the tranny. This is a costly fix (400 to 650, depending on the shop). The pressure valve (over time) wears a groove between the valve cylinder wall and piston (of valve) which allows tranny fluid to bypass thru the line, thus causing the hard shifting, mostly when the tranny is hot and the fluid is thin. Trust me when I say, no other fix will work, such as changing tranny fluid, flush and fill, or any additives such as Seafoam or other tranny slip or fix additives. Bite the bullet and find a tranny shop which will give you a LIFE TIME warranty, mostly, in case they install yet another defective valve.
