You know those little silver ***** in the tranny? I don't know what they do or what they are called but my friend thinks he left one out of the tranny when he rebuilt it with a shift kit. The tranny doesn't always go into reverse just right and takes time to catch, it also won't shift right into 2 and it slips real bad in first. the shifts aren't firm at all and all it seems to do is run the engine and not really go. LIke you can get on the throttle and rev to like 3 or 4k rpm and not get any response really at all. any help would be appreciated? thanx in advance guys.

 

Those are Check *****. They servo three functions, one is to close a hole off so that the oil is run through an orifice to control the flow and two is to separate two pathways for oil to flow. Third is to just close off a circuit.

 

so will those little ***** affect how the tranny is acting or not. oh yeah the tranny is a 700r4. i really need to get this thing going cuz i just got the new motor in and the tranny is not acting good and it is keeping me back from driving the camaro. thanx

 

come on guys i need some answers. i know someone has had this problem( i hope ) and has solved it ( i hope also). any help is great. thanx

 

You said he rebuilt it with a shift kit... did he rebuild it, AND put a shift kit in? Or, did he "just" put a shift kit in?

I think the answer is kinda obvious...either 1)the kit was not installed correctly,2) a checkball was left out, 3)you don't have enough fluid in the tranny.

If option 3) checks out, most likely you'll have to pull the pan again and go inside and recheck the install of the kit. (assuming it's just a kit installed, and not a rebuild as TomP asked)

Other thing I can think of is the TV cable could be unhooked causing pressure loss, but not sure if it'd that bad to cause youor problem.

 

hey guys thanx, i think that the guy left a checkball out. i am pretty sure the kit was installed properly cuz of the video that came with it. he got the tranny rebuilt before he put the kit in it. so i hope that is what it is. we are gonna pull the tranny AGAIN and see if that is what it is. lets hope. thanx again.

 

I had the exact same problem with my tranny when I put in a shift kit. Slipped in first, wouldn't shift into 2nd. The checkballs must be there for it to operate properly. My mistake wasn't forgetting to replace a checkball, but instead I had unknowingly bent the little roll pin in on the lever that was connected to the kickdown cable. The rollpin was supposed to move up the big gold checkball, but since it was bent, it didn't. He'd better pull out the valve body and make sure all the checkballs are there and in the right spots. The pressure regulator is the other likely thing that could cause a problem, so make sure all the parts are installed in it in the correct order, not upsidedown, and that the snap-ring is in the second groove.

It depends what ball was left out. The TV checkball won't make any difference as long as the cable is set properly and some others will just make for a rougher shift while others can make a drastic difference inhow the tranny works. Don't forget the possibility of the wrong VB gasket's, etc.

 

You can buy new valve body gaskets from GM. I bought them; they come in a set- you get the valvebody-to-plate gasket and the plate-to-case gasket. I think the set was under $15.

Also, SHEDVL has a good point about the pressure regulator; check the order of those pieces first, because you don't have to drop the valve body down. Remember the "second" groove is high up in the bore; you need to bottom out ("top" out?) the pressure regulator to see it. Although; I think if you went for the first groove, the pressure regulator would've spit out into the pan, and you wouldn't be getting the car to move at all.

That is a good point about the PR Valve setup. I have seen them not locked in place or the Int/Rev upside down. Theses cause odd problems depending on just where it lands. I don't know about a second groove though. It is either in the groove or not. I push up on the boost valve to make sure it will move up then push on the snap ring itself to make sure it WON'T move up!

 

If you do get a new valve body gasket from the dealership, you may need to cut/drill a hole or two into it. If you used a B&M shiftkit then you drilled an extra hole in the metal plate. You'll need to make the gaskets match it.
