Is the 700R4 still a mechanically controlled transmission?

Is the 700R4 still a mechanically controlled transmission?

The 700R4 is still a mechanically controlled transmission (with the exception of the locking converter circuit mentioned above), and depends physical pressure sensors and a sort of throttle position sensor to get it’s throttle position right.

What’s the difference between a 700R4 and a 4L60?

Well, the 700r4 uses a TV cable as the speedometer, and the 4L60 is an electronically controlled transmission, so if you see wires coming to the transmission on the rear of the transmission on the passenger side, you have a 4L60. The safest way of checking your transmission is to look at the identification tag on the transmission.

Why does my 700R4 have low transmission fluid?

If so you need to fill it back up and find where the transmission is leaking and fix it. Here is a whole post on low transmission fluid that may help. If your 700r4 is having a problem with harsh vibration going down the road, it’s more than likely loose torque converter bolts, or a driveshaft that needs balancing.

Why does my 700R4 have bad vibration going down the road?

If your 700r4 is having a problem with harsh vibration going down the road, it’s more than likely loose torque converter bolts, or a driveshaft that needs balancing. This is often a sign of a bad governor gear, or a TV cable that is not returning back when you let off of the throttle. Here is a pretty good resource on this subject.

What kind of transmission does a 700R4 have?

What does it mean when your 700R4 won’t shift?

700R4 won’t shift This is often a sign of a bad governor gear, or a TV cable that is not returning back when you let off of the throttle. Here is a pretty good resource on this subject. This is a pretty advanced problem for a shade tree mechanic and may be another one that you leave up to the professionals.

When was the transmission changed to the 4L60?

It is also very easy to find replacement parts for this transmission. The 700r4 transmission was not electronically controlled yet; it was hydraulic pressure controlled with a TV cable which acted as a throttle position sensor to control the gear shifting. In 1991~ the 700r4 transmission was replaced by the popular transmission 4L60.

What’s the difference between a 700R4 and a TH350?

The 700r4 and the 200-R4 transmission replaced the TH350 transmission at that year. The TH350 was a 3 geared transmission without the last overdrive gear. The 700r4 was a big upgrade with an additional gear (Overdrive), the 1st and 2nd gear became longer, and the transmission case itself became a bit longer.
