I rebuilt the 700 in my S-10 about 30,000 miles ago and it developed a strange problem. The torque converter clutch would slip under load - not a towing load, just squeezing into the throttle a little bit going down the interstate would do it (it wasn't unlocking - just slipping). Problem turned out to be a worn seperator plate. Where the check balls seat, two or three of the holes were worn and not letting the ball seal off entirely. I've never really paid attention to this part before since I didn't really consider it a "wear" part that needing replacing - not anymore.
This was the first really high milage transmission (305,000) I had rebuilt, so I learned on this one. I also put in a Transgo shift kit that I really like and it was really cheap ($27). It is part #SK-700 Jr. It is designed to mainly "fix" little quirks the 700 can develop over time and results in a very nice working transmission with a good shift, but not harsh at all. Not necessairly for competition use, but for a daily driver, I love it. Clay

The governor controls that.
DAMIT MAN! Laughing

Get dirty and calibrate that thing! It is so easy you don't have to pull the pan! A simple clip holds the housing.

It is a good tranny that gets a bad rep because of bad builders.

The Transgo kits are the hands down favorite among the reputable 700R4/4L60/E builders and the few good ones who don't use it basically make their own version of what Transgo does.

I like the Transgo stuff a lot better than the B & M stuff myself too. They seem to be a more in depth setup. The B & M kits seem kind of quick and dirty for lack of a better term. The kit I installed is designed to just "fix" problems associated with high mileage units that have been rebuilt or some of these problems can develop too. Stuff like torque converter shudder, slide - bump shifts, TV adustment not effective, etc. It wasn't really a detailed recalibration kit like their more expensive kits - so no it won't do anything to change shift points. I wanted this one because I just wanted a good working transmission in my truck, that's all. Clay

i just hear so many opinions on this
by the wat if your tv is not "set" you will not get the right rpm's out of a shift no matter how much you fiddle with the governor also the #1 reason for 3rd and 4th gear failure!!!!
the tv is the only way you control line pressure!!!!

besides af2 i will get my hands dirty 1 way or another
ive decided on the manual valve body!!!!!!!

Squeeeser I was telling it how it is! ( and being the smart ass I am) You can pull that TV cable till you cut you're fingers and never change the high rpm shift points! That being said I forgot to tell you about the governor? OR! Laughing

I don't really know what they were talking about TV adjustment not effective - that was just one of the things that was in the installation instruction list of things it corrected. I have personally never run into a TV cable setup that wouldn't show some change with adjustment - which all that is needed is full TV at w.o.t. so I don't know what there really is to adjust on a factory setup. On a 200R4 in my Nova, I modified the pivot point so it started off at a higher TV level under normal driving to raise shift points some, but it still wound up at full TV at w.o.t. Clay

The WOT shift is still accessed from the governor!
TV is correct and in first gear going to second relies on the governor! 2nd to 3rd is relying on the governor. And so on!

If the governor was set to shift at 4800 you will never change that with TV adjustments! Only governor! nothing else!
That said I relieve my self of further discussion! Good luck!
