Description

4L80E / 4L85E TransGo Reprogramming Kit, 1991-2013, 4L80E-HD2.

This 4L80E Performance Reprogramming Kit fits 1991 to 2013 General Motors vehicles equipped with 4L80E and 4L85E automatic transmissions.  Common complaints on these transmissions are no upshifts, soft 2-3 shifts, burnt direct frictions, broken hard parts as well as gear ratio and solenoid performance codes.

The boost valve assembly is notorious for wear causing both low pressure as well as runaway boost pressure. With the low boost pressure problem, the resulting complaints are a soft 2-3 shift, direct clutch failure as well as the gear ratio and solenoid performance codes. On the other hand, the runaway boost pressure problem can result in a costly broken case, direct drum and piston failure.
