Will a NP203 bolt to a 700R4?
To adapt a 203 or 205 to a 700R4, you can install this spacer OR use this shorter replacement output shaft. Once the length is taken care of the TH350 parts will bolt right up. If you’re installing an NP203 behind a 700R4, you will need this spacer and a TH350 to NP203 adapter.
Is a 700R4 the same as 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 strong is a 700R4 transmission?

Can I run a 700R4 without a computer?
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. Not just a simple kickdown cable like your TH350 analogue, the TV cable controls line pressure and shift points.
How many bolts are in a 700R4 transmission?
The 700r4 and the 4L60 transmission uses a bolt pattern of 16 bolts, so if the transmission looks like one of the pictures above and you can see 16 bolts, you do most likely have a 700r4 or a 4L60 transmission.
How to tell if a 700R4 cable is a 4L60 cable?
If you find 3 letters, the transmission is made between 1986-1993. The last way to identify if it’s a 4L60 or a 700r4 is to look at the rear of the transmission for the Aux TV Cable or wirings, as discussed before. Wirings = 4L60 Aux TV Cable = 700r4
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 should I do if my 700R4 transmission is slipping?
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 should always do when your transmission is slipping is to replace the transmission fluid and flush it. So the first thing I would recommend is to check the transmission fluid level.
