I remember the bad rep they got back in the 80s, when in reality if used properly they were a really good tranny. Sure Cure components are the same Sonnax parts sold individually to resolve common valve body complaints as well as other transmission problems. The high-quality Sonnax parts in each Sure Cure kit repair worn areas and protect the transmission against future damage. Does most of this info hold true for the 4L60E??? Once you get used to it, it's not big deal. The manual valve in 4L80E transmissions can break or wear the valve body because of its excessive length and thin stem diameters. Inhibits automatic transmission fluid oxidation and foaming. In addition, the piston can get cocked and gall the accumulator bore due to the pin bore wear or the spring bottoming out.
Lubegard Automatic Transmission Fluid Additive Prevents overheating. The new contact area is over two times the original and the pressure between the piston and the spacer is reduced by 60%. My truck started occasionally setting a P1870 code for trans slipping component. I have known the owner through my father since I was quite young he was on the same volunteer fire dept as my dad when I was a kid I forgot to ask what warranty they put on them, but I would assume at least a year. I think I will lean towards the full rebuild, hopefully next summer or so, and take it easy on the ole girl for now.
The United States Postal Service does not ship Liquids! The high-quality Sonnax parts in each Sure Cure kit repair worn areas and protect the transmission against future damage. A slightly higher shipping charge will occur - We apologize for the inconvenience! Eliminates torque converter shudder, also clutch chatters and shudders. We believe that by giving our customers a great shopping experience, sales will come on their own. Sonnax now offers an upgraded, redesigned manual valve kit, 34994-16K, which has lengthened spools with exhaust slots for increased bore support and increased stem diameters. The functions are done the same although some components used to do so are different. Extends automatic transmission fluid change intervals.
Description 4L80E, Sonnax Reverse Servo Spacer Kit. We believe that by giving our customers a great shopping experience, sales will come on their own. Saves a tremendous amount of wear on your reverse band, which as we all know is the weak link of the 4L80e. Rather than focusing on maximizing profits, we focus on maximizing the service that we provide and providing the lowest prices possible. Strength, holding capacity, and durability. There are absolutely no special tools required to install this kit.
Sure Cure components are the same Sonnax parts sold individually to resolve common valve body complaints as well as other transmission problems. The special ingredients provide high thermal stability to the friction material. That's our promise to you! They are basically the only shop around that plow guys and performance guys take their stuff. Sonnax has provided a replacement end plug to ensure proper hydraulic control. Repeated reciprocation of the accumulator piston causes wear at the piston pin bore interface. Email Us: Call Us: 1-877-782-5582. Have questions about this specific product? I tried to argue with them, saying that if something mechanical were broken, it would fail all the time, not some of the time.
The United States Postal Service does not ship Liquids! If people only knew to put them in 3rd when towing or plowing, a few million of those trannies wouldn't have died prematurely. Just hard to get used to a R-3 shift. Yes it applies to the 60E's also for the most part. Due to a design change in 1996, the reverse servo commonly breaks because it is stressed more than early servos. Your Order can only be shipped via FedEx. Product Details Sonnax Part Number: 34994-16K 4L80E manual valve kit.
In addition to general rebuilding tips and technical information, the technical book also includes vacuum testing information and locations at other key areas within the valve body. We have developed our corporation into one of the leaders in the industry. I don't have that option. Just doing this on any truck prolongs the life of the converter alone. Rather than focusing on maximizing profits, we focus on maximizing the service that we provide and providing the lowest prices possible. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume.
For guys that aren't aware late model transmissions use aluminum valve bodies and most use steel spool valves in those valve body's. There's many things that can cause the 1870 code but few of them have to do with the mechanicals in the trans, more like a control issue in the valve body from worn spool valve bores. Same way with lockup in 3rd, you can and do have it but it isn't providing an overdrive. My understanding, and how it's been described to me by transmission experts, suggests that 3rd or 4th can be used either in lockup or out, hence my statement. For me it will be only a local rebuild or Jasper. Like anything else the steel valves stroking in an aluminum bore tend to wear the bore to the point that you begin to have leakage around the spools and thus you end up with misdirected and lowered fluid supplies and pressures to the components.
