This 4L80E transmission for sale is also popular for LS swaps, big-block builds, diesel conversions and for replacing a TH400 when you want an overdrive.
Matching the Right Version
- Early or late: 1991-96 and 1997-up units differ in connector, internal harness, filter and valve body parts.
- 2WD or 4WD: long tailhousing for 2WD, short output for the transfer case on 4WD.
- Converter: gas and diesel converters differ in stall and bolt pattern.
- 4L85E: if your build sticker shows MN8, you have the heavier-duty 4L85E. Tell us before ordering.
- Controls: factory trucks use the PCM or a TCM. Swaps need a compatible controller.
Send us your VIN and we confirm all of this before your 4L80E transmission for sale is shipped.
How to Identify a 4L80E
If you are not sure what is in your truck, these points help before you order:
- Pan: a long, irregular pan held by 17 bolts. A 4L60E pan is squarer with 16 bolts, and a TH400 pan has 13.
- Bellhousing: cast into the case. There is no separate bell to unbolt.
- Length: around 26 inches, a few inches longer than a TH400.
- Electrics: one large round case connector plus input and output speed sensor plugs.
- Build sticker: the RPO code MT1 in the glovebox or on the door means 4L80E, MN8 means 4L85E.
Swappers often buy a 4L80E transmission for sale to replace a TH400 in an older truck. The bolt pattern is the same, but the extra length means moving the crossmember or shortening the driveshaft, and you need a controller to run the electronics. Plan for those parts when you budget for the swap.
Not sure? Send photos of your current transmission and pan with your VIN, and we will tell you whether this 4L80E transmission for sale is the right match.
How We Check Every Unit
Before any fairly used 4L80E transmission for sale goes out, we check:
- Fluid colour, smell and debris on the pan magnet
- Input and output shaft play
- Case, bellhousing ears and tailhousing for cracks
- Case connector for fluid seepage and bent pins
- Input and output speed sensors
- Donor history where known
See our tested used engines page for how we inspect parts.
Why Choose a Fairly Used 4L80E?
The 4L80E is one of the strongest automatics GM ever put in a truck, and a healthy used one still has a lot of life left. A rebuild can take a week or more and the bill grows with every hidden problem. A good used 4L80E transmission for sale gets a work truck, van or tow rig moving again in a day or two, for much less money.
Common Reasons People Replace a 4L80E
- Stuck in second gear (limp mode) that remains after wiring repairs
- Slipping under load or when towing
- Burnt fluid and worn clutches from overheating
- Worn pump and case bushings causing low pressure
- Converter shudder or no lock-up
Check the connector, harness and speed sensors first, because they cause a lot of 4L80E faults. If the problem is inside the box, this 4L80E transmission for sale is a direct replacement.
Installation Tips
- Flush or replace the cooler and lines.
- Seat the torque converter fully onto the pump.
- Inspect and replace a cracked flexplate.
- Clean and seal the case connector and check the external harness.
- Plug in both speed sensors.
- Fill with DEXRON VI, cycle the gears and check level hot.
- Clear adapts with a scan tool so shifts relearn.
Towing and Big Power
The 4L80E handles heavy trailers well as long as you keep it cool. Fit a large external cooler, keep the fluid clean and watch the temperature on long climbs. Many people run more than the factory torque rating with a good converter and cooling, but if you are building serious horsepower, plan for upgraded internals. For engine options, see our Vortec 8.1 engine and Chevy LS3 engine.
For a fairly used 4L80E transmission for sale that does real work, change the fluid and filter every 30,000 to 50,000 miles and keep the connector dry.
