What years did GM use 700R4?

Are all 700R4 the same?
No, not all the same. There are quite a few varieties. There are a couple of different bolt patterns; the 60° 6-cyl one, the Chevy V8 one, maybe others. Among V8 ones, the “core” is the same, within a given year, but there are many small differences in the governors, servos, and other parts.
Can you run a 700R4 without a computer?
There are no TV cable, mechanical speedometer drive, or governor provisions. To run a 700-R4 trans behind a carbureted engine without a computer, at the very least the TV cable must be hooked up to the carburetor and properly adjusted.
What is the difference between a 4l60 and a 700R4?
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.
Will a 700R4 bolt up to a 396?

When did GM change the transmission of the 700R4?
GM renamed the 700R4 to 4L60 (4-speed Longitudinal 6,000 lb GVWR) in 1990, even though it was the same transmission without any significant changes. However, there was an enhancement to the 4L60 in 1993 where it was electronically controlled instead of hydraulically with a TV cable.
What kind of tailhousing does the GM 700R4 have?
The key distinction of the 700R4 / 4L60 / Early 4L60-E (from the Later 4L60-E) is the four bolt rear output or tailhousing / adapter pattern. The Later 4L60-E has a six bolt “hex” rear bolt pattern and a removable bellhousing. There are three main castings of the 700R case. One is the standard car version.
What to do when your 700R4 transmission won’t lock?
When your 700r4 Transmission is slipping or won’t lock, it’s most likely a problem with the converter inside the transmission. However, the first thing you always should to when your transmission is slipping is to replace the transmission fluid and to flush the transmission.
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.
