Uncover 2-3 shift flare causes on 4L60-E transmissions with current-draw testing, including the possibility of a faulty computer. For reference the stock torque rating for the 4L60E is 360 ft/lbs and 380 ft/lbs for the 65E. What I do is replace the accumulator piston with an aftermarket one and use the accumulator springs from an older 700r4 shift kit then I "adjust" the servo so that it has between 1/16"-1/8" (closer to 1/16" the better) of travel inward before it stops moving. The shift points move as they should, the truck thinks it's going slower so the shifts are at a higher speed than stock. Seems like its going into 3 every time, but it only takes 1/8" more forward and that would be in. Probably WON'T set trouble code. i'm not sure if this is indicative of faulty solenoids in the pan, or a larger issue. 3 with green/blue pcm) my 4L60e has started acting up. The aggregate demand curve illustrates the economy's demand for all goods and s. I had the transmission rebuilt 20k miles ago, about 400 miles post rebuild I ran into a 2-3 slip (same as before the rebuild), though mostly at low engine speed. Overtime, transmission fluid breaks down and loses its friction properties, and this causes slipping symptoms. One of the most common signs of a clogged transmission filter is abnormal shifting. Before I buy and take the trouble to change this, is this why no reverse? I can understand it being the 1-2 shift, but does it control reverse. 4L60E no overdrive, all other gears fine. Sometimes when installing a corvette servo, there might be at issue with single. One of the most common is the complete failure of 3rd & 4rth gear. Oil Pump (4) Stator shaft bushings scored or off location. Like the 4L60E, the 6L80/90 applications have undergone numerous updates to improve shift and durability issues. No 1st or 4th gear (torque converter doesn’t lock, can be driven in 2nd, 3rd, and Reverse gear): Transmission is in “limp home” mode or lost electrical power. If you own a 1997 GMC K1500 with a 4L60E transmission and it's going into “LIMP MODE“, the following may well be the cause for the problem. He would put the shift leaver into 2ed, the man shift into D after he got up to. Autozone, Advanced Auto, or O'reilly can scan/read your check engine code. Never reduce the 1-2 accumulator piston stroke. INstalled factory TPS switch to carb linkage and is sending / receiving proper signal. Problem - A common 4L60E transmission problem is an intermittent hard 1-2 shift, often accompanied by engine bogging. Here are the details of what I eventually found and how I arrived at the diagnosis. The 4L60E transmission, a well-liked automatic gearbox found in many GM automobiles, is renowned for its dependability. You're having an issue with the forward clutches or the apply piston. In reality, There's no one size fits all type recipe like I developed for 4L60E's with active 3-2 downshift & control valves, Though I can give some experienced educated starting points.
