At the track I also up shift in the burn out stage so that it doesn't shift up by itself and kick out of the burn out. In the staging lane I keep it in 1st but when I take off I slide it into drive when I feel I have the www.doorway.ru Interaction Count:  · The governor will shift the transmission as you speed up. Some transmissions have a manual type and others use an electronic type. Either way, it is in the tail shaft area of the transmission and will need to be checked to see if it is stuck and not working correctly by an .  · A 4l60e is a r4 - the only difference being that one shifts electrically and the other shifts hydraulically. The 4l60e shifts with electronic shift solenoids. GM figured out it was easier to control the transmission electronically than via the hydraulic circuits. Plus you can change how the trans shifts while driving, which can be a real benefit for some engines.

4L60E Transmission Only Shifts Manually. If the transmission only shifts manually (and therefore doesn't shift automatically), there is probably a problem in either the PCM or one of the related sensors sending information to the PCM. This could be the VSS (vehicle speed sensor) or the TPS (throttle position sensor). Another contender that can now be added to the list of possible causes for shift flare on a 4LE is a bad computer. This month's problem vehicle is a GM truck with a flare on the shift before and after overhaul, with no trouble codes. The shop installed a second valve body with all solenoids but it didn't help. Manual 2nd (Figure 2) When you shift the manual lever to manual 2nd, manual low pressure exhausts, which releases the low/reverse clutch and exhausts the pressure from tube 1. This allows the spring to push the shift valve into the upshifted position. In this position the shift valve supplies pressure to apply the servo for second gear.

In the staging lane I keep it in 1st but when I take off I slide it into drive when I feel I have the traction. If he starts the truck in 1, it in fact is in first gear. It can be manually shifted to 2nd, 3rd, and then into 4th but will not automatically downshift if he decelerates. If it is manually downshifted, then it will downshift. (Basically, I have a manual transmission right now without the clutch pedal). A 4l60e is a r4 - the only difference being that one shifts electrically and the other shifts hydraulically.
