What is the difference between a 4L60 and a 4l80 transmission?
What is the difference between a 4L60 and a 4l80 transmission?
The 4L80E is larger and heavier than the 4L60E. Its more hefty build can be tied to its 236 lbs and a length of 26.4″. Alternatively, the 4L60E weighs 150 lbs (without fluid) and it has a length of 23.5″. A comparison between the size and weight shows that the 4L80E is significantly larger and heavier.
What is the difference between a 4L60 and a 4L60E transmission?
The biggest difference between the 4L60 and 4L60E is how they are controlled. The 4L60E is controlled by a computer, while the 4L60 is controlled by a TV cable. If you were to try to put a 4L60E where a 4L60 once was you’d have to buy an aftermarket transmission controller for it.
How much horsepower can a 4L60E transmission handle?
Their Stage 2 Pro Race transmission can handle gobs of power while their Invincible Black Edition 4L60E trans can support over 1,000 ponies.
Why are 4L60E a bad transmission?
The problem you are having with yours is a very common problem. It involves the valve body and a worn TCC regulator valve. This worn valve is causing the converter clutch to slip and chatter, overheating the trans and burning the fluid.
Can a 700R4 replace a 4L60E?
No 700R4 transmissions were ever controlled by the ecm. The lockup function is grounded with the ecm, but not the shift points like the 4L60E that replaced it. Any 700R4 will work in any application.
What year is the best 700R4 transmission?
1987
Is a 4L60E better than a 700R4?
700R4: The Good And The Bad. Shifting over to the 4L60E side, the main advantage of this transmission is that electronics eliminate the need for a TV cable and that whirling dervish of weights and springs to establish shift control.
Is a 700R4 a good transmission?
The 700R4, produced by General Motors/Hydramatic, is considered one of the best overdrive transmissions ever made. This transmission had a lower first gear ratio, which was good for performance at low vehicle speeds, while the 30% overdrive provided significant fuel economy improvement.
How much HP can a 700R4 handle?
The Street/Strip 700R4 is good for about 550 hp maximum, but with the HD input drum it is good for about 625 hp max. Add another $240.00 for the input drum.
Can you run a 700R4 without a TV cable?
Than again my 700R4 is at FB right now getting redone as my last builders was out to lunch with his recommendations. Basically, if you haven’t figured it out from the posts above, the answer is “Yes.” If the transmission is in park you can run the engine without worrying about the TV connection.
How can you tell if a 700R4 is good?
Find one that has the dipstick in place and look for signs of leaks. The vehicle from which the tranny is being pulled should give a clue to its reliability. Ask for at least a partial refund if the tranny is found to be bad. If you find at least a 85+ tranny it’s a good core to rebuild.
Which transmission is better 350 or 700R4?
The th-350 is a bolt in swap with aftermarket parts, but in your case there is no reason to go th-350. The 700r4 has a deeper 1st gear which around town, red light to red light you will love, also has the over drive gear. The th-350 is lighter, and stronger, but no OD and not as deep of 1st gear.
What years did Chevy use the 700R4 transmission?
The four-speed Turbo Hydra-Matic 700R4 was introduced for the 1982 model year for use in Chevrolet/GMC vehicles. In 1990, the Turbo Hydra-Matic 700R4 was renamed the 4L60.
How much does it cost to rebuild a 700R4 transmission?
Automatic transmissions are not filled with magic voodoo no matter what the local transmission shop tells you. We called around to see what a rebuilt TH700R4 would cost us if we brought the unit down to the local shop and had them go through it. We were quoted prices from $550 to $1,500.
Is it hard to rebuild a 700R4 transmission?
It just takes time and patients though. That’s because the 700R4 got a bad reputation, and hasn’t lost it yet. When it was first introduced, it wasn’t very durable, and it’s much more complicated to rebuild.
How do I make my 700R4 shift harder?
By drilling out a few holes in the spacer plate, installing a larger servo (553) and a larger boost valve, the transmission will shift quicker & firmer. Getting a 553 servo should be easy as many V8 folks remove them to upgrade to the 093 (Vette) servo (offer ten bucks for one).
What does a shift kit do 700R4?
In short, an automatic transmission shift kit modifies the transmission’s shift timing in order to dramatically increase shift firmness and durability of the transmission components. Transmission shift kits can reduce this overlap time while improving the overall shifting action.
Are shift kits bad for your transmission?
The slipping of the clutches causes heat inside the transmission and we all know heat is the #1 enemy of a trans. A shift kit reduces the slippage, which is why the shifts are firmer. With less slippage, there is less heat buildup. This IS better for the trans.
Will a shift kit hurt my transmission?
A shift kit will firm up the shifts by making them happen faster. There is less clutch slippage, and the trans could have a longer life. Some shift kits can also change the rpm where the shifts happen. This could give you much better performance, but it could hurt your fuel economy.
What speed should 700R4 shift at?
Currently shifts from 1st to 2nd at about 4500 and from 2nd to 3rd at about 4800. The weights and springs on the servo are changed to move the shift points around. The TV cable can also play a small part in shift points.
Why does my 700R4 shift late?
The TV valve can cause late shifts if worn badly. IF the TV cable is not adjusted correctly , it will shift late.
How does a 700R4 transmission shift?
The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. When the TV cable is properly adjusted the movement of the TV plunger in the valve body is calibrated to the movement of the fuel delivery system.
How do you install a transmission kickdown cable?
Method 1 of 1: Replacing the kickdown cable
- Materials Needed.
- Step 1: Jack up the front of the vehicle and set the jack stands.
- Step 2: Place wheel chocks on the rear wheels.
- Step 3: Disconnect the kickdown cable at the carburetor or throttle body.
- Step 4: Remove the kickdown cable from the mounting bracket.
What does the kickdown cable do?
One component that helps both drive systems communicate is the kickdown cable. This device helps the engine relay information on revolutions per minute (RPM) to the automatic transmission and essentially tells it that it’s time to shift gears.
