pressure control solenoid
 

Does anyone know about the pressure control solenoid??

kcusscam and I have been talking about it. And I am woindering if anyone else is famliar with this part.

How hard is it to get to??

Can it be fixed easily??

I need help,

Tim

Re: pressure control solenoid
 

The Pressure Control Solenoid Valve regulates transmission line pressure. The PCM controls the PC solenoid valve based upon various inputs including throttle position, fluid temperature, MAP sensor, and gear state.

kcusscam and I have been talking about it. And I am woindering if anyone else is famliar with this part.

The transmissiom case side cover has to be removed to gain access to the PC solenoid valve, this is a labor intensive job.
I would tend to think not, it is a labor intensive job. Why do you question the PC solenoid valve, is there a DTC set?

The reason I question it is because kcusscam and I have been talking about it.
When I described the problem in my post he said he'd had the same problem and he believed that was what was wrong.

Is it something I can get by without doing for awhile??

I normally fix whatever is wrong with my car when it goes wrong but the 4 bills repair charge he spoke of scares me.

My car is driving fine, it just tweaks my melon that something is wrong with it.
My car is the other woman in my life :lol:

Anyhow thanks alot for your help Mark

Oh yeah there is no DTC set.

Coming into this one late. Doesn't this control the line pressure and how the car shifts?

You have to remove the side case cover first...

1. Disconnect the negative battery cable.
2. Install the engine support fixture.
3. Remove the air intake duct.
4. Remove the shift cable and bracket at the transaxle.
5. Remove the accelerator and cruise control cables from the retainer on the left strut tower.
6. Unbolt but do not remove the ABS modulator.
7. Raise the vehicle. Refer to Vehicle Lifting.
8. Remove the left front tire and wheel assembly.
9. Remove the inner splash shield.
10. Remove the tie rod end from the knuckle assembly. Refer to Tie Rod End Replacement - Outer in Steering and Suspension.
11. Remove the stabilizer shaft link from the lower control arm. Refer to Stabilizer Shaft Link Replacement in Steering and Suspension.
12. Remove the ball joint from the steering knuckle. Refer to Lower Ball Joint Replacement in Steering and Suspension.
13. Remove the drive axle from the transmission and support axle. Refer to Wheel Drive Shafts Replacement.
14. Remove the pinch bolt from the steering gear intermediate shaft at steering column. Refer to Intermediate Steering Shaft Replacement in Steering and Suspension. Caution: Failure to disconnect the intermediate shaft from the rack and pinion steering gear stub shaft can result in damage to the steering gear or to the intermediate shaft. This damage may cause loss of steering control, which could result in an accident and possible personal injury.
15. Remove the intermediate shaft from the steering gear. Refer to Intermediate Steering Shaft Replacement in Steering and Suspension.
16. Remove the three frame-to-body bolts on the left side.
17. Loosen but do not remove the bolts on the right side.
18. Remove the transaxle oil cooler hoses at the case. Refer to Automatic Transmission Oil Cooler Hose Replacement.
19. Lower the vehicle and loosen the engine support fixture adapters until adequate clearance is available at the case side cover to frame rail area.
20. Raise the vehicle.
21. Remove the case side cover bolts.
22. Remove the case side cover (53).
23. Clean the case and side cover gasket surfaces.

Then...

# Disconnect the transaxle wiring harness.
# Remove the pressure control solenoid
1. Install the pressure control solenoid (322).
2. Connect the transaxle wiring harness.
3. Install the case side cover. Refer to Case Side Cover Replacement.

1. Inspect the case side cover for the following conditions:

o Damaged or porous gasket sealing surfaces
o Damaged or porous casting surfaces
o Damaged or stripped bolt holes

2. Install the new gaskets (54 and 59) on the case (53).
3. Install the case side cover.
: Refer to Fastener Notice in Service Precautions.

4. Install the new side cover bolts (56) and one side cover to case stud (58) in the locations shown. These bolts will properly locate the case side cover to the case.
5. Install the remaining bolts:

o Nine case side cover bolts (56)
o Four side cover torx bolts (57)
o Four side cover to case stud bolts (58
o Tighten the side cover bolts to 25 Nm (18 ft. lbs.) .

6. Install the transaxle oil cooler hoses to the transmission. Refer to Automatic Transmission Oil Cooler Hose Replacement.
7. Raise the transmission and frame using a transmission jack so that the frame bolts can be installed.
8. Install the three frame-to-body bolts and tight the right side bolts.
9. Remove the transmission jack.
10. Install the intermediate shaft to the steering gear and the pinch bolt at the intermediate shaft. Refer to Intermediate Steering Shaft Replacement in Steering and Suspension.
11. Install the drive axle to the transmission. Refer to Wheel Drive Shafts Replacement.
12. Install the ball joint to the steering knuckle. Refer to Lower Ball Joint Replacement in Steering and Suspension.
13. Install the stabilizer shaft link to the lower control arm. Refer to Stabilizer Shaft Link Replacement in Steering and Suspension.
14. Install the tie rod end to the knuckle. Refer to Tie Rod End Replacement - Outer in Steering and Suspension.
15. Install the inner splash shield.
16. Install the left front tire and wheel assembly.
17. Lower the vehicle.
18. Remove the J 28467-360.
19. Install the shift cable and bracket at the transaxle.
20. Install the accelerator and cruise control cables from the retainer on the left strut tower.
21. Install the ABS modulator.
22. Install the air intake duct. Refer to Air Cleaner Intake Duct Replacement in Powertrain Management.
23. Connect the negative battery cable.
24. Check the fluid level. Refer to Fluid Capacity Specifications
25. Inspect for leaks.
26. Check front end alignment.

The TSB that explains the problem...

A/T - 4T65E Harsh Shifts/Shudders/Slips/DTC's Set

File In Section: 07 - Transmission/Transaxle

Bulletin No.: 0O-07-30-002B

Date: July, 2002

TECHNICAL
Subject:
Slips, Harsh Upshift or Garage Shifts, Launch Shudders, Flares, Erratic Shifts and Intermittent Concerns, DTC P1811 or P0748 Set (Replace Pressure Control Solenoid Valve Assembly)

i got mine replaced by the dealer for 600$ can.

And i had that hardshift on light load. Was feeling like a shiftkit :D

Basically, Yes 8)

................................Wow :shock: That is one huge job! that's what I meant when I said labor intensive alright.

Labor intensive is right! I got worn out just reading it. ;)

To loosen the bolts mentioned in 16 & 17 one has to remove the lower front splash shield.

Also nothing is said about the transmission to body frame mount. The two parts are held together by a single nut & gravity. Three bolts secure the transmission half to the side cover. One would think that that needs to be removed before unbolting the side cover.
