Question about 2004 Chevrolet Tahoe

Delay in shifting when excelerating

04 tahoe Z-71 5.3L Z-motor auto transmission approx. 79,000 miles. It started with diagnostics showing fuel pump faulty (replaced worked fine for a month) then check engine light came on again this time showed 2 of the O-2 sensors bad both replaced and ran fine when mechanic performed drive test. When I left and was driving back home the hesitation isn't as bad but can tell now sinces it's not sputtering and no response when excelerater pressed that the transmission has a delay shifting gears. fluid levels verified all show good. Approx. 5,000 miles ago had injectors cleaned and transmission fluids and filter changed. The mechanic (pep boys) seem to think it may be a "shift sensor" (unable to find such a sensor in any manual or on-line) could it be called something else or could it be something else all together?

    what do you mean has a delay in shifting? how long of a delay? is it slipping slowly into gear, or just not shifting for a few seconds then going in normally

If my throttle potion sensor is bad on my 2007 chevy tahoe over time can that cause my transmission to go?


I doubt it.
The sensor could make the transmission not know when to shift, but not much else.

P1776 is the only code you need to be concerned with it a problem with the solenoid back (not the transmission valve body) Also did you recieve the transmission reflash that the dealer are supposed to do? And this is why you are dealing with a delay engagement (by the way its not second gear its 3rd)

Trooper will not excelerate. it only kicks in


the car will not accelerate, check distributor unit, wires, cap and rotor making sure they have clean contact between the pole. test coil making sure you have strong 12V. Check air mass flow sensor, this unit also connected to ECU unit and also control the shifting along with transmission rotation sensor, both work in sync with one another. Check fuel pump for proper pressure my disconnecting the fuel line from the fuel filter, cover the line with a pieces of clothes, using your thumb, apply it on top of the fuel line and have a friend turn engine over, make sure you have the fuel line pointing downward away from your face. feel the pressure of the fuel pump does get weak over time and loose some pressure. if changing replacing fuel pump good idea to also replace fuel pressure regulator. Check fluid in tran mission making sure it has proper oil level. being 1990 im sure it has over 100k, I would have the tranny flush and filter change with new oil. Its good idea to have tranny flush every 75-100k especially SUV. tranny pressure sensor may need replacing, sometime it get clogs up with wast particles from gasket and worn filter. Battery light come on one awhile, have your alternator check, weak or faulty alternator will also cause battery light to come on.
