Pan bolts are 8mm x 1.25
Shift linkage lever & Converter to flywheel are 10mm x 1.5
Valve body, TV cable & speedo are 6mm x 1.0
Trans mount & tail housing holes are 10mm x 1.5
American (US) threads are "not close" like some people think. Use the correct nuts & bolts! When you buy a tranz from a rebuilder or wrecking yard ask for all the needed bolts.
This is NOT a kick down cable as a T-350 has. It is a throttle valve cable for internal main line pressure modulation of the 700 tranny. Hook the cable up or burn your tranny up fast!
Notice the casting line that is shaped like a "rainbow". It flows through the upper cooling line fitting. This is a good indication that you have a 700/4L60 trans that is new enough to have the good parts in it.
Stamped in this area is a row of numbers and letters. The "first" character stamped in should be a number and is a very reliable number of the year of manufacture. 1982 was the first year of a 700, but the number "9" was used for some reason.
After that GM used matching numbers for the year of manufacture. A "3" would be a 1983 unit , etc.
There are more numbers and letters stamped into this area after the first number that I will not explain here since it is not necessary to find the year of the trans.
If the 700 you are looking at has a pad area that has been ground smooth, it may be from the unit being a factory rebuilt unit at one time. A tag is usually attatched to the trans case by the authorized rebuilder. This tag may or may not contain correct year info. Sometimes I have seen a year of rebuild ( ie:1989) but the case is an earlier year. This is something you find out when the pan is removed!
About 2 inches behind the ROUND 2 - 4 servo is the connector for the PCM.
