2002 3.4L GrandAm with automatic, shifts hard during normal driving, has been serviced with new filter and proper fluid and level. This problem started after the intake manifold was removed for gasket replacement.
I had the same problem in my 2002 grand am GT. After taking it to a transmission shop and them telling me that I had all this stuff wrong with it that was going to cost me about 2700$ I looked elsewhere. I had an Intake Temperature Sensor that had went bad. It was registering on the check engine light after the fact. I changed it and then found out there was a loose wire in the connector. I fixed that and havent had a problem with it since

2002 pontiac grand am rack and pinion replacement how to
Removing the rack and pinion assembly from a 2002 Pontiac Grand Am Se
To get the old rack and pinion off of the car for replacement involves lowering the sub-frame, removing the stabilizer bar, and pulling the rack out from the driver side of the vehicle.
Important: Get an alignment! Not only is it dangerous to drive with your steering out of align but it will also grate the tread off your tires in a matter of weeks or even days.

how do you change a thermostat in 2002 pontiac grand am
with motor cold, follow the top radiator hose to motor,there will be housing at that end of hose close to motor.remove the 2 bolts @ remove the thermostat housing. remember which way you remove the thermostat from that housing, replace with your new one and reverse these directions to put back together. i would also recommend a new gasket with new thremostat.a little rtv or some people call it blue glue might also be needed.when removing the thermostat from housing you may have to remove the top hose also.befor you start, remember fluid will come out of hose and the housing, be prepared with something to catch that fluid.

looking for a 2.2 ecotec timing chain diagram with pictures
Getting the timing chain back on these engines can be tricky and requires more than just a diagram to get right. Here is how the timing chain should be reinstalled. Keep in mind that
this engine can cause damage to the valves if the timing chain has any
problems while the engine is running so it may not be a bad idea to
setup the timing system as follows and do a compression test to make
sure that everything is in order there.
Install the crankshaft sprocket with timing mark at the 5 o'clock
position. Lower the timing chain through the opening in the top of the cylinder
head. Carefully ensure that the chain goes around both sides of the
cylinder block bosses (See 1 & 2 in picture): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412535.gif
Install the intake camshaft sprocket with the INT diamond at the 2
o'clock position. Hand tighten a NEW intake camshaft sprocket bolt. Route the timing chain around the crankshaft sprocket with the matching
colored link aligning with the timing mark. Route the timing chain around the intake camshaft sprocket with the
uniquely colored link (1) aligning with the INT diamond: http://gsi.xw.gm.com/image_en_us/gif/000/000/466/466558.gif
Install the timing chain tensioner guide through the opening in the top
of the cylinder head. Tighten the timing chain tensioner guide bolt to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412160.gif
Install the exhaust camshaft sprocket with the timing chain matching
colored link (3) at EXH triangle aligned at the 10 o'clock position: http://gsi.xw.gm.com/image_en_us/gif/000/000/466/466570.gif
Ensure the timing marks and the colored links (1,2,3) are correctly
aligned: http://gsi.xw.gm.com/image_en_us/gif/000/002/003/2003412.gif
Use a 24 mm wrench to rotate the camshaft slightly, until exhaust
sprocket aligns with the camshaft. Hand tighten the NEW exhaust camshaft sprocket bolt: http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412536.gif
Install the fixed timing chain guide. Tighten the fixed timing chain bolts to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412165.gif
Apply sealant, GM P/N 12378521 (Canadian P/N 88901148) compound to
thread and install the timing chain guide bolt access hole plug. Tighten the chain guide plug to 90 N·m (66 lb ft): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412164.gif
Install the timing chain upper guide. Tighten the timing chain upper guide bolts to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412167.gif
Inspect the timing chain tensioner. If the timing chain tensioner,
O-ring seal, or washer is damaged, replace the timing chain tensioner. Measure the timing chain tensioner assembly from end to end. A new tensioner should be supplied in the fully compressed non-active
state. A tensioner in the compressed state will measure 72 mm (2.83 in)
(a) from end to end. A tensioner in the active state will measure 85 mm
(3.35 in) (a) from end to end.
****If the timing chain tensioner is not in the compressed state, perform
the following steps. Remove the piston assembly from the body of the timing chain tensioner
by pulling it out. Set the J 45027-2 (2) into a vise. Install the notch end of the piston assembly into the J 45027-2 (2). Using the J 45027-1 (1), turn the ratchet cylinder into the piston: http://gsi.xw.gm.com/image_en_us/gif/000/000/797/797246.gif
Inspect the bore of the tensioner body for dirt, debris, and damage. If
any damage appears, replace the tensioner. Clean dirt or debris out with
a lint free cloth. Install the compressed piston assembly back into the timing chain
tensioner body until it stops at the bottom of the bore. Do not compress
the piston assembly against the bottom of the bore. If the piston
assembly is compressed against the bottom of the bore, it will activate
the tensioner, which will then need to be reset again. At this point the tensioner should measure approximately 72 mm (2.83 in)
(a) from end to end. If the tensioner does not read 72 mm (2.83 in) (a)
from end to end repeat the steps required to return it to it's compressed state above.
Install the timing chain tensioner. Tighten the timing chain tensioner to 75 N·m (55 lb ft). Use a suitable tool with a rubber tip on the end. Feed the tool down
through the camshaft drive chant to rest on the timing chain. Then give a
sharp jolt diagonally downwards to release the tensioner: http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412158.gif
Use a 24 mm wrench to hold the camshaft. Tighten the NEW camshaft bolts to 85 N·m (63 lb ft) plus 30 degrees: http://gsi.xw.gm.com/image_en_us/gif/000/000/630/630311.gif

transmission pressure switch manifold fault explanation p1810
Hi there:
The automatic Transmission Fluid Pressure (TFP) manual valve position switch consists of five pressure switches (two normally-closed and three normally-open), and a transmission Fluid Temperature (TFT) sensor combined into one unit. The combined unit mounts on the valve body.
The Powertrain Control Module (PCM) supplies ignition voltage for each range signal. By grounding one or more of these circuits through various combinations of the pressure switches, the PCM detects which manual valve position you select. The PCM compares the actual voltage combination of the switches to a TFP manual valve position switch combination chart stored in memory.
The TFP manual valve position switch cannot distinguish between PARK and NEUTRAL because the monitored valve body pressures are identical. With the engine OFF and the ignition switch in the ON position, the TFP manual valve position switch indicates PARK/NEUTRAL. Disconnecting the AT inline 20-way connector removes the ground potential for the three range signals to the PCM. In this case, with the engine OFF, and the ignition switch in the ON position, D2 will be indicated.
When the PCM detects an invalid state of the TFP manual valve position switch circuit by deciphering the TFP manual valve position switch inputs, then DTC P1810 sets.Action Taken When the DTC SetsThe PCM illuminates the Malfunction Indicator Lamp (MIL) during the second consecutive trip in, which the Conditions for Setting the DTC are met.The PCM commands D2 line pressure.The PCM commands a D4 shift pattern.The PCM freezes transmission adapt functions.The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.The PCM stores DTC P1810 in PCM history during the second consecutive trip in, which the Conditions for Setting the DTC are met.Since the computer does not know what gear range the transmission is shifted into, it defaults to a higher line pressure to protect the transmission. It also commands the transmission as if it were in the D4 position. The transmission will still shift normally through all the gears, shifts may be more firm than normal. No damage will occur to the transmission if driven even for prolonged periods with this dtc set. It is far more likely that the loss of transmission fluid damaged the transmission.
Hope helps.
