How to rebuild a 4l60e transmission

  1. Try spreading out the hard parts on the Performance Automatic build bench. Note that the 4L60E doesn’t look different from the 700-R4, 4L60, 4L65E, or 4L75E transmission. You just need to take this abused 4L60E and give it a better rebuilding capacity with improvements from Performance Automatic
  2. Note that this particular 4L60E was significantly trashed with a succession of every broken hard part. The Performance Automatic is going to be built in 400-500 horsepower and a better torque capacity.
  3. Remember that one of the 4L60E weakness is the factory sun reaction shell. This tends to break around the hub which doesn’t take much time for it to fail. The Performance Automatic fits its 4L60E building with this improved, thicker sun shell (left) which is with a stronger, welded center hub and a radiuses spline area that prevents failure. Note that a heavy-duty Torrington bearing helps to reduce friction in this area upon rebuilding, which also reduces heat.
  4. The Performance Automatic help increases 4L60E torque capacity with a five-pinion front planet (left) and ring gear.
  5. Meaning, with the five pinions instead of four (right) you will be spreading torque across the more mechanical surface area. The 4L60E will handle about 400-500 horsepower with the five-pinion front planet. This is about 20 percent more torque capacity.
  6. The rear planet torque capacity will be increased by 20 percent with a five-pinion planet (left) and ring gear instead of the 4L60E’s vanilla four pinions (right). However, this will take your 4L60E about 400-500+ horsepower torque capacity and around 6,500-7,000-pound gross weight when rebuilding. Note that this gives you the capacity of the 4L65E/4L75E.

How long does it take to rebuild a 4l60e transmission?

A lot of vehicle owners ask ‘’how long does it take to rebuild a 4l60e transmission’’? The truth is that someone needs to know the exact condition of your vehicle first to answer this question. However, the estimated time should be about 8 hours, and to rebuild the transmission, you need an additional 6 hours.

So how much does it cost to rebuild a 4l60e transmission?

In case you are planning on taking it to a repair shop for rebuilding, this means you have to pull and bring the transmission to them, then it’s possible to have it rebuilt for $1000 or under. 

But the repair shop pulls it, rebuild, and reinstall the transmission, then it can cost anywhere from $2000-$4000.

Why is the 4l60e a bad transmission?

This is because the 4L60E happens to be a four-speed, electronically controlled automatic transmission that is used in light-duty trucks manufactured by General Motors (GM). Although, most automatic transmission diagnoses and repairs are beyond the knowledge of local mechanics, and also, you can still diagnose some minor problems without specialized tools or training. 

However, such a diagnosis simply means you have to recognize and isolate the symptoms of a specific malfunction before you can decide which repairs are really necessary.

How do I know if my 4l60e is bad?

As we all know, transmission failure cannot happen without a warning. This simply means that there are various warning signs that your transmission’s going bad. 

Below ere are 10 transmission symptoms you should be aware of.

  • Weird Smells
  • Some strange Sounds
  • Noisiness
  • Check Engine Light
  • No Response
  • Fluid Leaking
  • Clutch Drag
  • Shaking
  • Won’t Go Into Gear
  • Slipping Gears

What transmission can replace a 4l60e?

Note that the 4L60E transmission has been used before in a slew of 1/2-ton GM trucks and SUVs, and it has also been used in some GM 3/4-ton trucks. This is because it’s a transmission that has proven itself a workhorse. But you can chose to replace it with a much beefier 4L80E four-speed automatic transmission.

Can a 4l60e handle 500hp?

Yes, but you will need to first upgrade all the standard soft parts, and also the hard parts if you intend to have that much power put through it.

The most important thing is the torque you are putting into it, if it’s built right and you keep it cool, then it should last a while.
