4R75E Transmission Rebuild Cost
Automatic transmissions, like the 4R75E, have proven tough and reliable. They can run for hundreds of thousands of miles under the condition that they are properly serviced.
Taking care of the 4R75E transmission means performing a complete rebuild every 30-40 thousand miles, which will help you avoid common problems.
Here is a complete 4R75E transmission rebuild cost, all the necessary parts, and an overview of the disassembly process.
How is a 4R75E Transmission Rebuilt
The 4R75E is a complicated transmission model that professionals should only handle. Automatic transmissions like the 4R75E are more challenging to understand than manual ones, which makes them harder to repair and rebuild.
The disassembly process
The process involves the removal of the transmission from the vehicle and completely disassembling it.
The disassembly process starts from the bottom. The input and output sensors are removed, followed by the transmission fluid pan and filter. Then the internal wiring is disconnected from the electronics.
The accumulator and servo pistons are removed from underneath, after which the manual shaft, park assembly, and EPC solenoid are removed.
The process continues on the transmission side by removing the clutch assembly, overdrive band, input, reverse drum, and all the gears inside the transmission body. The last part being removed is the output shaft.
After the disassembly, all parts and the transmission body are inspected to check for defects. Substantially worn-out parts must be replaced with new ones, while those in good condition can be reused.
4R75E Transmission Rebuild Cost
Now that you know how the 4R75E transmission is disassembled, let’s look at how much it costs to rebuild it.
The best choice for any transmission is to perform a full rebuild using a complete rebuild kit. A rebuild kit will cost less than purchasing each part separately.
4R75E transmission rebuild kit parts
When choosing a complete 4R75E transmission kit, then it should contain the following parts:
- Complete set of seals, gaskets, and o-rings for the transmission and valve body
- Metal Clad Seals
- Bearing set
- Bushing set
- Four high-energy frictions and steels for the intermediate clutch
- Four heavy-duty frictions and steels for the reverse clutch
- Five heavy-duty frictions and steels for the forward clutch
- Six high-energy frictions and steels for the direct clutch
- Overdrive band
- Reverse band
- Reverse servo
- Overdrive servo
- 1-2 accumulator piston, spring, and cap kit
- 2-3 accumulator piston
- Intermediate clutch spiral lock kit
- Fluid Filter
The average price of this rebuild kit is around $500, depending on the brand
Additional options can also include a:
- Hardened intermediate stub shaft
- Higher quality pan and pan gasket
- A new electronics kit (torque converter solenoid, shift solenoids, and EPC solenoid)
- A rebuilt torque converter
- A six-plate forward clutch kit
- A seven or eight plates direct clutch kit
The additional cost for these optional parts is around $800-1,500 The dismounting, disassembly, and installation process will cost around $500. This depends mainly on the company and the experience of the mechanic.
Therefore, the total 4R75E transmission rebuild cost usually falls between $1,000 and $2,500.
