All of our transmissions are fully remanufactured and are held to the highest and strictest industry standards. What this means to you is the fact you are getting a quality product that meets or exceeds the OEM standards, not just a part that is taken apart and “patched”. We ensure that all the current updates are performed, during reassembly each unit is ran through tests to ensure correct assembly and quality.

Updates to the Transmission:
- Updated TransGo Actuator Feed Limit Valve
Also included is the TransGo Actuator Feed Limit Valve which requires a special reaming tool, that re-bores worn out aluminum 4L80E valve bodies which is typically an issue when time for a rebuild, and allows installation of this special high quality valve. This problem is the NUMBER ONE most overlooked issue by other re-builders. One indicator of this issue is the 2nd gear starts, 3rd neutral condition, no 4th gear, codes 68, 85, 86, and 87 and direct clutch breakage. The OEM actuator feed limit (AFL) valve has a large reaction area and is greatly affected by side loading, which wears the valve body bore. The EPC solenoid oscillates the torque signal and AFL oil, which increases valve action. As bore wear increases, oil pressure is reduced to the shift solenoids, which causes solenoid and ratio codes. The same AFL oil loss results in lower line pressure. If this valve is not installed, even after a rebuild transmission can have these issues and can lead to transmission failure the P1870 Code. If this valve is not installed, even after a rebuild transmission can become overheated and as a result can burn up quickly do to torque converter slippage, caused by the badly worn valve body casting in the converter clutch regulator valve bore.
- Superior Shift Correction Package
This shift correction kit corrects with these common issues: Runaway high pressure, Erratic pressure rise, Converter lock-up shudder. Inconsistent shift feel, Shift solenoid filter blow-out, and Premature unit failure
A complete pressure regulator valve train is supplied in the 4L80-E kit. This corrects Fail-safe, runaway high pressure that will crack the case if not corrected. The PR valve train supplied in this Shift Correction Package will stop runaway high pressure before it happens.
This transmission comes with a 1 Year 36,000 Mile Warranty with the purchase of a new torque converter. We offer an extended Warranty 2 Year 50,000 Mile Warranty, or a 3 Year 100,000 Mile Warranty for an additional charge.
Buyer is required to swap a GOOD core for this trans otherwise there will be a core charge in addition to the above price. Core must NOT have any hard part, or case damage, otherwise there will be additional charges for hard part damage.
We also have Remanufactured Torque Converters available for $275
Majority of units are in stock, if we do not have one in stock they are quickly available in most case, as little as one day. There are many different version of this transmission model available so please call for additional details.
