yea, Extreme is closer to me than the guy in Illinois. but i'm going to price both ways just to get a ballpark
Absolutely. See who'll best serve your needs and work within your budget. Extreme has an excellent reputation.
I have a copy, very through and lots of pics. I sent it to guy who used it with the good parts from CK. It only has a few miles but behind a 400+ hp and 500+ ft/lbs, mild 9 to 1 422ci Olds 350 stroker motor.
here is some info on 200-4r trannies.

heres an excerpt.
DECIPHERING THE CHART CODES:
The transmission application tag is located on the passenger side rear of the transmission on the case just above & forward of the trans mount.
1982-1985 transmissions use a two letter code on the tag & 1986-1990 transmissions use a three letter code with an "F" at the end of the code {there may be other letters but all the 86-90 transmissions I've checked have an "F"}.
1982-85 transmissions use a 13 digit numbering system to show what it is & when it was built. These numbers are on the bottom of the transmission tag below the letter code {EXAMPLE: 123 2T85CQ1234}. The first three digits are the Julian date {the date the transmission was built, julian date is the start of trans production so 001 would not be january 1st. The 4th digit is the Plant Shift the transmission was built {1=1st shift; 2=2nd shift; 3=3rd shift}. The 5th digit may be a letter or number & is the code for the Hydramatic plant that the trans was built at. The 6th & 7th digits are the model year of the vehicle the trans was originally installed in. The 8th and 9th digits are the two letter code of the transmission & denotes internal parts & valve body calibration of the unit. The 10th through 13th digits is the serial number of the unit.
1986-1990 transmissions use a 15 digit numbering system {EXAMPLE: 9 123 2T86CZF 1234}. The 1st digit is the Calender year the unit was built. The 2nd,3rd, & 4th digits are the Julian Date {see above}. The 5th digit is the Plant Shift the trans was built. The 6th digit is the Hydramatic plant the trans was built at. The 7th & 8th digits are the model year of the vehicle the trans was installed in. The 9th & 10th digits are the two letter code of the transmission & denotes internal parts & valve body calibration of the unit. The 11th digit is the letter "F". This denotes that the trans is a 200-4R {GM decided to add a third letter to the code that will show what transmission family it is, 200C = "B", 200-4R = "F", 700-R4 = "M", etc...}. The last 4 numbers are the serial number of the unit.

Jack I'm thinking about picking this up for my valve body/governor swap,you're welcome to it when i'm done as i know you've got a build in the future.
Thank you very much, Chris,
Sure let me know. I'm sure it has a wealth of information in it and will be very helpful putting my trans back together again. We'll talk more
Money well spent for me. I didn't do everything in the book and did some things that weren't in the book. I also have a copy of the atsg overhaul manual and a book GM put out called Principles of Operation. http://www.ckperformance.com/View/2004R-PRINCIPLES-OF-OPERATION-SECOND-EDITION This one is more for those who just want to know what magic is going on inside the unit.
If you are having it built I wouldn't spend the coin on any of em. If you are of the cloth that wants to give it a try the ck manual is the one I would spend my money on.
I think if you can remove and install a trans you can probably overhaul one. There are some special tools needed but there are ways to get around that. Let me know if you need more info.
