What does MD 8 mean on a transmission?
The TH700R4 was first used in GM cars and trucks in 1982, designated as a Hydra-Matic MD-8 transmission, and this MD-8 is also cast into the bellhousing. Another way to identify one of these units in the car is by the square, 16-bolt oil pan.
When did the 700R4 transmission come out in the US?
The 700r4 Transmission came in the year of 1982. The 700r4 and the 200-R4 transmission replaced the TH350 transmission in that year. The TH350 was a 3 geared transmission without the last overdrive gear.
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.
What’s the problem with the OE on a 700R4?
A chronic problem with both OE and thicker aftermarket shells is failure when splines continue to strip or the shells break under normal conditions. Use of a updated hardened spline sun shell helps prevent. It is common for the plastic accumulator piston to wear or crack and older aluminum piston bores to wear from repeated reciprocation.
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.
