Would that be the cause of the solenoid replacement to not correct the problem? As a bonus, they come with upgrades to prevent or cure common problems that the factory should have fixed in the first place! This motion is caused by continuous rapid fluctuations of fluid pressure, impact of a valve against the end plug face and spring forces where the end plug face is utilized as a spring seat. No claims for labor, shipping or consequential damage will be accepted. Now, after reading borland's post I noticed I forget a step. Immediately after that repair, the truck developed a leak at the converter housing apparently the fluid was foaming. The pressure control solenoids have a bushing that needs to be replace because they get sticky and contaminated.
Not much help here, I know. What is not covered under this warranty: removal or installation costs, damage due to accident, misuse or alteration, damage due to improper installation. Current mileage is 75K miles. These replacement bushings are not cheap so most places do not replace them. If you get no reading that means the solenoid has failed due to a break in the internal coil wiring. The dealer never replaced the filter; that might have attributed to the early failure. Install new solenoid body pack and tighten bolts to 71 in-lbs.
Remove pinch clamp, and refill with new Mercor V. This transmission has many different problems that cause hard shifts and engagement problems the solenoid pack usually fix a lot of them but not all of them. Delayed engagements occur as the converter feed is reduced with excess bore wear. I might be bringing this thread back, but I have a question on part numbers. These Flow Control Upgrades virtually eliminate front planetary burn-up due to lack of poor or no lube.
Here's the deal sorry if this sorta hijacks the thread a bit but I figured since we're on the same topic there was no need to start another thread. If you ever have any issues with any of our parts please contact us. So, it's a mistery to me. This solenoid will not fix transmission with internal problem, valve body problems or computer problems. Also need to relearn the shift engagements and shift timing. There is an easy and inexpensive way to check your solenoids to see if they are bad. Only about 4 qts drained.
But the replacement didn't help, my tranny is still having shift problems between 2nd-3rd. Line pressure will be reduced as the circuits between line, converter and exhaust wear. Telco, Removing the solenoid pack doesn't require removing the valve body, it sets right next to it. As line pressure goes up, servo covers and pistons have excess pressure in reverse. The kit works in either modulator control bore location. Most importantly we address the main issue with the pressure control solenoids.
So I replaced the solenoid block again. I actually just got back from my friends place where we did the same. Additionally, the bore surface and end plugs can erode over time due to high pressure fluid squeezing between the bore and end plug. Correction: Refurbish the valve bore and install the Sonnax oversized valve kit to restore proper hydraulic function and prevent future leakage. The assembly also includes a case-hardened plunger valve with self-centering annular groves, a replacement spring, and larger O-ring for improved sealing.
All information deemed reliable but not guaranteed. Test drove the vehicle afterwards about an hour ago and it's still behaving exactly as before. Correction: This drop-in-place assembly includes a harder canister with more support for the plunger valve, which prevents sticking. There's also a pressure relief valve at the main pump that could be leaking off pressure. Going to add some Lucas trans additive to it tomorrow to try and Band-Aid it along for now. This Sonnax kit works in either modulator valve location. Specs Bearing Style: Enclosed Material: Hardened Steel Outer Dia.
All returns must have prior company approval and authorization. All returns must have prior company approval and authorization. It is a 5 speed transmission designed for rear wheel drive vehicles. This new system also furnishes a built in cooler bypass system that if the unit is extremely cold when fluid starts to gel or in the event the cooler is blocked or restricted, flow to the parts still occurs - protecting your transmission. Correction: The Sonnax sleeve is made from highly wear-resistant aluminum, and allows the case to be refurbished to provide proper clearance with the servo apply pins.
