Does a 700R4 have a lock up converter?

Does a 700R4 have a lock up converter?

The GM 700-R4 & 200-4R transmissions utilize a lock up converter to help create a more efficient transmission. It takes stress off the fluid coupling of the torque converter and it helps decrease the amount of heat being generated at higher cruising speeds.

Are 700R4 and 4L60E torque converter the same?

You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4. The good news is that either way, you win.

How does a 700R4 torque converter lockup?

How to Wire a Switch to Lock Up the Torque Converter on a 700R Transmission. Torque converter lockup on the 700R4 transmission is controlled by the TCC solenoid. When the solenoid is engaged, fluid is applied to the torque converter clutch, creating lockup and a direct link between the engine and transmission.

What does a torque converter lockup switch do?

If you’re unfamiliar with exactly what the torque converter lock up is or does, the easy answer is, the lock up clutch takes stress off the fluid coupling of the torque converter and it helps decrease the amount of heat being generated at higher cruising speeds.

How do I know if my 700r4 has lockup?

To tell if the converter is locking up in the early GMs try this- Once at interstate cruising speed(no load other than cruising) , very lightly touch the brakes with your LEFT foot, while maintaining your current speed and accelerator position.

Can a torque converter lock up an engine?

There are basically three ways a torque converter lockup clutch can fail: It can stay locked up, stalling the engine when the car is braked to a stop; it can never lock up, which shows up as an increase in fuel consumption and radiator temperature; or it can slip when engaged, allowing engine speed surges at a constant …

Can you swap a 700R4 with 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 does torque converter lock up feel like?

When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it’s vibrating. Your car will vibrate even when you’re not going very fast. The shuddering makes the car lag and is very noticeable.

Is there a torque converter for a 700R4 200-4R?

” Power Raptor Lock-up Torque Converter 700R4 2004R” Fits 700R4, 200-4R and non-LS1 4L60E transmissions. This is a 10 inch converter with a 12 inch lock-up carbon fiber clutch rated up to 700 horse power. Can be ordered in stall speeds of 2000 to 4000 RPM.

What kind of torque converter do I need for a 4L60E?

The MegaRaptor-2L with its carbon fiber clutch will withstand power levels of 1000 horse power. This 10 1/2 inch converter can be ordered with stall speeds of 2000 to 5500 RPM. Fits 4L60E, 4L65E and 4L70E transmissions, 1998 on with a LS1 type motor.

What’s the difference between a 700R4 and a 4L60E?

You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4.

How does the overdrive work on a 700R4?

Using the connectors at the end of the switch, 12 volts is sent to lock up the 700R4 torque converter when the plunger is pushed in (brake pedal not applied – left). The ohmmeter shows continuity. Depressing the brake pedal interrupts the 12-volt power and unlocks the converter (center). The ohmmeter shows continuity is lost (OL – open loop).
