K_ code 200 4R transmissions

[corsa65]

I have decided to go with a 200 4R transmission over the 700R4 for my 82 G-body Oldsmobile with H.O 305. The 200 4R is a 1986, and of course, it is NOT a "B" code transmission. If memory serves me correct, it is a "K" code as it came from an Oldsmobile with the highly sought after 307

Internal condition appears to be good due to the fact that upon pan removal, I found it to be very clean. I, unfortunatly am NOT flush with cash, so I would like to use this transmission (after I tear it down to more closely inspect and replace a few items).

I am going to guess that the calibration of the valve bodies of these "K" code transmissions could best be described as "soft and mushy" and is due to various factors, and I just bet that the G.M. engineers also played with the valve body spool diameters as well. My question is this. Will the addition of a good shift programming kit (such as Transgo), and a different governor assembly improve the shift quality at all? Or is this valve body unsalvageable? I see that TCI offers a valve body that is "BRF Calibrated" but for some reason this statement makes me a tad nervous. Any input would be greatly appreciated.

Got your reply. I will know for sure tomorrow about the valve body as I will be at the shop. I will get the numbers off the valve body AND transmission case, and let you know as per our talk on friday morning. Will also get the rear end ratio. I found very little "pack" or band material in the pan upon inspection, although I DID find a couple of minute peices of what appears to be steel in the pan. One peice was located in the very rear, small, pan sump (below the governor) and 1 in the front, large sump. I have seen broken accumulator springs in 200 4R's before, and maybe this is what I am looking at. (the stator shaft is also "worn") Ahhhhh, can you say "KUALITY MATERIL"

I will be mailing you a money order for the manual on tuesday. Hope you are having a good holiday!
