OK...there has to be someone here that can make sense of this throttle valve thing. Just installed a newly rebuilt 700 R4. I put it in gear, and I go nowhere. Checked and double checked everything...but this TV has me puzzled. What is the proper procedure for adjustment? I mean..nothing happens no matter what gear I put it in. I would really appreciate some feedback on this.....the thought of pulling it out again is really depressing....

 

It does not move in any gear or reverse?
:confused:

Perhaps it is more than jsut not having your tv cable properly adjusted. Who rebuilt the trans? And who installed it?

 

doesn't budge in any gear,,,,not even a hint. Alocal Corvette shop rebuilt it...I installed it.

 

How's the fluid level?

 

FLUID LEVEL CHECKS OUT ok...This is weird...these guy's (who rebuilt it) came highly reccommended, Hell, I should hope so...700 bucks plus my old core. I can't see where I've doone anything that would cause this during the .

installation

 

The TV cable adjustment will not stop it from moving when it's put in gear.
Does reverse work? If not, it's an indication of a total loss of fluid pressure.

Of course, I am assuming it has been properly installed with all linkages and wiring correctly connected.

What kind of torque converter did you get?

 

What do you mean what kind? I HATE TO SOUND DUMB, BUT ALL i KNOW ABOUT A/T's would fit on half a sheet of TP. Please...clue me in...

 

Also...what would cause a "no fluid pressure" situation? Just from an installation stand point? And yes...all the wireing and connections are positive....TC was full of fluid, and I added 4 quarts to an empty tranny pan.

 

My best advice would be get a hold of the rebuilder.

 

 

The TV Cable shouldn't have anything to do with it going into gear.

Assuming(and thats saying a lot with Tranny shops) that the transmission is rebuilt right, here is what you might have done.

1. Throttle Linkage installed on the wrong transmission bolts. This would cause the linkage to not move the valves correctly. But something should happen if this is done.

2. Throttle Linkage not installed.

3. Torque Converter not bolted to flexplate.

4. TV Cable not hooked on transmission end. Pull on the cable, if it springs back, its hooked.

I don't want to sound condescending, but you did say you don't know anything about auto trannies. There is more to installing one than putting in the six engine mount bolts, and two torque tube bolts.

If the above four things are ok, the car should at least shift into reverse/drive. If it won't, you need to contact your builder. $700 is a great deal. I paid $850 for my bench rebuild plus $150 for a decent torque converter.

 

A dry 700R4 takes 11 quarts of tranny fluid to fill it up.
Even if your TC was full of fluid I think you would still be low after putting in 4 quarts.
Fluid level must be checked with engine running and tranny in Park.

Good luck

 

You need more fluid (like said above). Check your dip stick and Ill bet its dry. With out the fluid it wont move.

 

If you ask my opinion, there are only two things that will obviously affect the trans the way that you describe. One is to have low or no fluid going to the pump. The other is to not have the torque convertor bolted to the flywheel. If the shift cable were not hooked properly to the valve body in some way, you would not get the proper feel of the valve moving thru the detent positions. The TV cable would not have the effect that you describe. On a worse case scenario, it would be a faulty assembly of the trans clutches which would not allow the clutches to engage properly. OR perhaps a pump that was not examined and was already broken but was reused anyway. I suspect that if the fluid level is correct and the torque converter is bolted up properly, you have a pickup tube in the pan that either fell off or was improperly installed. Or perhaps a plug in one of the passageways was left in during reassembly of the internal parts.Plugs are sometimes used to keep foreign objects out while internal parts are being installed. The plug would prevent fluid from going to the pump.

A competent shop does not make these kind of mistakes in reassembling a trans during the rebuilding process. But it does happen. SO either they are incompetent or you have a freak problem. I would contact them and see what they think. Perhaps you can explain in detail what you did and they can double check your work. If it is their problem, I am sure that they will fix it without any cost to you. This includes dropping the trans and reinstalling it once the problem is fixed. That is, I should stress, if they are a competent shop. I would give them the benefit of the doubt before you do anything drastic and call them.

Good Luck! Let us know the results.
:seeya

 

I just got done rebuilding my own 700r4 out of necessity...
first off, you need allmost 3 gallons of fluid in the tranny 11.5 something quarts....
second off, IF the shift rod to the controll valve was not installed the tranny may be suck in any spot, neutral being one of them...it's inside the pan, easy to overlook when installing brain onto case....
another thing is to look for obvious metal parts in the pan, I didn't have a snap ring in properly, even though it LOOKED ok, it wasn't...and the pump pressure regulator valve blew out of the pump and into the pan...zero line pressure....fun to get into the pump again with tranny fluid dripping into your face, rest assured of that....
except for a myhrid of problems like that, sneakey things, the tranny is really fairly straight forward in it's assy....but would help to have experience....things to look out for...

Same here mrvette. I installed a shift kit, and even though the snap ring looked OK, it blew out the regulator when I started it up. No damage, just a PITA to drop the pan and reinstall it.

 

Low Fluid :confused:
Tourque converter not engaged into the pump :confused:
Tranny line to the cooler blocked :confused:

 

And the diagnosis was.......

He sent me a message that he pulled the pan and found out that no filter was installed. I guess someone forgot to put one in. That explains why no oil was being sucked in to the pump. No FLuid, no workee........

:lol:

 

That is why ALL Vettes should've come with a manualt tranny. I had my auto 88's tranny rebuilt by the supposed best. The car wasn't done for over a month and had gone on and off the rack 7 times when I initially went to pick it up. The shop was a good 3 hours from LA so that got old real quick. The company's name is BowTie Overdries in Hisperia CA. I would rate the rebuild itself as a 8 and the install as a -9million!!!! They welded a damn extra bracket to my TB and hacked up my harness, broke the VSS port and dicked the exhaust up severely. It is true that yoiu pay for what you get.
Good luck,'

I did the same thing... IMO The instructions don't stress enough that it need to be seated in the second grove.
