Repeat Steps 3 through 9 six (6) additional times. 6L80E Torque Converter Power Raptor Full Size Non-Billet Number 88-6L80-1, now with Billet Cover Option. Engine torque rating increases minimally, but the output torque rating of the transmission jumps up by nearly 220 ft. lbs. The question is will the 10L80 be as strong as the 10L90? 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. vehicle weights. Then, of course, Sixth gear is still 0.75:1 overdrive. At this point, the converter rebuilder is faced with either finding another core that he hopes will have good components or purchasing a Sonnax forged cover GM-CC-13 and forged piston GM-DA-17P. For a type B code, the fault must be present after two consecutive ignition cycles, otherwise, the MIL will not illuminate (however, a pending code will store). When diagnosing this unit, it is very important to realize that the failure management programs built into the powertrain system may be a direct reflection of the customers drivability complaint. I also have a 2wd 2006 Trailblazer SS with a forged 416ci stroked LS3 which makes around 600 hp or so with a Yank SS3600 stall converter. When cutting the JMBX open, converter rebuilders report that a high percentage of units show extreme damage due to the clutch piston and front cover crashing into each other (Figure 1).

With a dry weight of approximately 230 lbs, its also very light considering the complexity. This idler gear and ball bearing assembly is mounted to the stator shaft support housing. The small 10-speed gear steps allow the engine speed to drop to lower values than it would in the 6-speed transmission, providing for the best fuel economy. So, what's the unique problem with the 6L80, 6L90 converter found in full-size vehicles? You also asked about GMs new 6L80E. Shift the transmission to Reverse.

This transmission makes an excellent conversion transmission due to its adaptability into most Jeeps longer than CJ5s. Maximum shift speed is 6500 RPM. Upon a test drive and a scan, code P0741 is noted and the percentage of TCC slip shows to be way out of range. Your cooperation with this program is greatly appreciated. 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. The high pressure oil pump inside this transmission is incredibly complicated for no visible reason. TRU-STREET 10L90E TRANSMISSION W/ 1800 STALL LOCK UP CONVERTER. By reducing the rpm drop between gears, the engine remains within its power band. It began replacing the 4L60E transmission in many vehicles starting in the 2006 model year.
