Unlike previous shift solenoids, they are mechanical in nature in that no transmission fluid passes through them (Figure 2). And you are correct the converters in these units are experiencing a high percentage of failure and are more problematic than normal. This drives up the price of the rebuilt converter, but ensures that this kind of failure wont happen again. TAP-2000 is a floor mounted shifter with Tap up Tap Down for GM 6/8L80/90E transmissions. To handle the increased output torque capacity, the 6L90 departed from the long-standing GM 32 spline specification output shaft of the 6L80 and went to larger diameter 29 spline for most truck applications. Conceptually, locking the converter should help the mph trap speed by reducing slippage. Smith began writing for Car Craft magazine in 1979 and became editor in 1984. GM 10L80: A new kind of pump noise. Before answering that question, its worth noting the role that Sonnax plays in the converter rebuilding business. The transmission lacks a direct-drive, but features two overdrive gears. Even though it has two more gears, creative packaging allows the 10L80 transmission to be no bigger or heavier than an 8L90 or 6L90. We had to use a spacer from Advanced Adapters but otherwise they are the same. Objectively, it is a fairly simple repair: simply remove the transmission pan, remove the valve body, unbolt the TEHCM from the valve body and install the new one. Can I assume my car has the General Motors GL80 with the 4.02 first gear? Sonnax highlights two product lines for helping with heavy solenoids for GM/Ford 10L/10R and 9T series transmissions. A second electric 10L80 pump maintains fluid pressure when the stop/start function activates.

So why does the JMBX converter have this chronic problem? Retiring Early The Transmission Industry Has Been a Dream Come True, A two-piece valve body with eight solenoids. $3,245*. January 2022 Jason, MAZDA6 shuts down while driving fuel pump not monitored, may be no engine light etc. The 6L90 transmission is slightly longer and taller than a comparable configuration 6L80 due to its beefier internals. The overdrive ratio thats added is 0.75:1. The HydraMatic can be adapted to the popular Jeep transfer cases, including the: Essentially all factory GM 4wd applications available with an OEM configured 6L80 have adapters and transfer cases that are prohibitively long for a Jeep, and transfer cases whose sizes and gearing fall short of desirable for most Jeep applications. What is most welcome about it is that it is a very durable, functional and impressive transmission assembly and appears to have a terrific prospect with GM and the aftermarket community. Become a 6L80-E and 6L90-E expert now!

I see where Summit Racing lists a TCI transmission that was originally a 4L80E but they list it as a six-speed transmission. Sticking valves and sticking CIDAS solenoids are becoming more common concerns with these units. As you build the best transmission that you can for your customer, you should consider including an updated torque converter in the repair estimate. The dealership was able to provide this part rather quickly. Thought's? Change Your Address, Yes, I would like to receive emails from Gears Magazine. But once he had the parts and the job was complete, the noise issue was resolved, confirming the cause to be the idler gear spinning around the ball bearings outer race. Also since the transmission is different the gearing and tuning are naturally different. Brian at Tommy Boys Performance, however, has the opportunity to work with a local dealership assisting them when their workload gets heavy. My problem with the 4L80E is it was always a workhorse and in the past 25-30 years trucks have gotten much quicker and versatile. I am interested in enhancing my vehicles performance. Will it be like the 5th gen's where the ss got the 6L80 and the more powerful ZL1 got the 6L90? It is a heavy-duty version of the 6L80 six-speed automatic, with a strengthened input gearset which has two additional pinion gears for six total, and a strengthened output gearset, that uses wider gears than the 6L80. As transmission builders know, it can be difficult to determine a root cause when you are looking at a catastrophic failure, with rotating parts crashing into each other. (incl.

The 4L60E was the first generation of transmission to work with a Gen III Vortec or LS motor. The 6L80 was approved for use in these vehicles weighing up to 8600 lbs. It's meant to be used with rear-wheel drive and it requires 8.4 quarts of fluid. By utilizing more gearing, the 6L80 keeps the car in its power band longer, improving the MPG of the vehicle between 4-7% (over the previous generation fours speed transmissions) depending on the configuration of the vehicle that its in. LS 3 has a Big Turbo on it, I am only worried about rear gear, rest I have help with, Car never went over 130 or it red lined with Big Block, Never was a highway car, It has a 373 or a 323 in it, Not a 411 I know that much, Thats all, Im building a gen one Camaro and Ive purchased lt4 supercharged motor for it I was wanting to know if you know the difference in size for 10 speed transmission to a turbo 400 I need to know how much to raise my floor pan at tunnel and about how much fire wall to cut out. Indirectly affects shift pressure control. Since buying the car I have been trying to learn a bit about the auto trans. Applications. Repeat Steps 3 through 9 six (6) additional times. The 6L80 / 6L90 TEHCM is located inside of the transmission on the 6L80 / 6L90 valve body. The Sonnax forged covers and pistons are designed to be flat and will stay that way through the forces of converter welding, miles of driving and varying input torque from the engine. DESIGNED FOR GEN V LT1 & LT4 ONLY. You know where this is going yup, its the converter. - Scope testing the Ford 10R80. By the time a converter rebuilder opens up a JMBX, the damage is done, and it can be hard to see what happened first. The band number is printed on the solenoids in the location shown and will be a 1, 2, 3, 4, or 5 (Figure 3). But its interesting to note that there is a very low cover/piston failure rate for the 4L60-E TMBX converter. All rights reserved. The 8L90E is an 8 speed automatic transmission developed by General Motors and introduced for the 2015 Model year. As an example, combining the TCI Six-speeds 2.97:1 First gear with a 3.50:1 rear gear ratio is equal to a traditional TH-400 (or stock 4L80E) with a 4.19:1 rear gear. Although the basic engineering is the same, the GM 10L80 and Ford 10R80 each have proprietary control software, along with a few other differences that are suited for each specific application. I work on other peoples vehicles for a living. The 6l80 was designed to handle the torque output of some of GM's biggest late-model LS (gen 4) and LT (gen 5) v8 engines, but a number of design flaws created most of the common 6L80E transmission problems. As the 10 speeds continue to make their way into our shops, keep in mind the more you know about them, the better off youll be.

Every modern GM vehicle has one of these sheets in its glove compartment. By combining a wide 7.39 overall gear ratio spread, with smaller steps between each gear, this GM 10-speed automatic transmission is able to keep the engine in its ideal power band during acceleration. While not new to the 6L80, it uses an Input Speed Sensor to monitor input speeds to compare against engine speed and Output Shaft Sensor speed, using this data to adjust shift speeds under instantly detectable conditions. To achieve this flip-flopped damper orientation in the JMBX, the profile and shape of the piston is radically different from the TMBX. Its interesting how the new 8- and 10-speed automatics have essentially turned the traditional powertrain ratio scheme 180 degrees. Respectfully, Len Gilbert Kitchener ON Canada.
