Hi all.

I want to remove the plastic Electrical Case Connector from the side of my 200c autobox, *however I do not wish to remove the transmission from the car*. Will it just pull out ?

According to my 82 GM workshop manual Section 7 / 200c-9 , you need to compress two plastic fingers, obviously from inside the box, allowing the connector to slide out. You then unplug that from the actual lock up solenoid. However, I do not want to go along that route ...

Basically has anyone here ever just used a pair of pliers / grips and pulled the connector out without damaging the internal plastic fingers or the o-ring seal ?

The last thing I want is any bits of plastic breaking off and falling inside the transmission - then I really would have to remove the transmission.

I apologise in advance if this question makes absolutely no sense to anyone.

cheers !

 

Might be able to drop the pan and get in that way to collapse whatever fingers in there that hold it in. Probably have to anyways because of the wiring. Why are you doing this anyway?

 

Thanks for that.

My car has the 2-pin plug with corresponding two-holed gearbox socket / terminal ( I think this was only found on the 82 version, all the others I think have the 4-pin terminals with 3 wires ) However only one of the recesses (holes) on the gearbox connector socket appear to have an electrical terminal inside it to allow it to connect to the 2-pin plug coming from the front of the car - it's basically a hole with nothing inside it and I am wondering if this is correct or not.

I would have thought there would be two terminals, one in each of the holes. I know that on cars equipped with the 4-pin connectors / sockets, if you look at the socket on the gearbox, only three of the holes have terminals inside them , one for each wire. The forth is just a blank, empty hole.

It just appears that only one of the wires is being allowed to supply power to the solenoid and the other wire is doing nothing as it has no means to connect to the solenoid, due to a missing terminal ?

A previous owner has done alot of machete-ing to the wiring on my car, the tcc solenoid being one of the casualties ( the plug had been cut off altogether !! I was able to obtain a new plug thanks to one of the members here ), however I am slowly but surely putting things right.

I hope this makes sense - that's basically why I'm doing this, to visually inspect the socket for damage.

 

My stock '82 200c is still sitting in the garage... if I can get around it tomorrow, I'll pull the pan off and have a look. Maybe take some pictures too hehe. Still haven't had a look inside after my torque converter split open. Probably not much if any fluid left in the case, all went on the roadway

 

Thanks alot for your help EvilCartman - sorry to hear about your torque converter - now for me that *would* be a nightmare - I honestly shudder at the idea of opening up an automatic gearbox - I just don't want to go there .... !!!!

You've given me a great idea - although I can't actually see up alongside the socket at the side of the box due to lack of room - the transmission tunnel gets in the way - I could get the digital camera up there and take a quick snap - that would tell me if the terminals are intact inside both holes or not.

I suspect that only one of the holes contains a terminal. I recently put a piece of wire inside each of the holes to see if I could 'feel' anything there or not - I couldn't move it around at all in one hole, due to the terminal being there, but the other hole appeared to be totally empty with nothing inside ..... doesn't look too good I reckon.

I've got a picture of a 4-pin terminal taken from the outside of a gearbox showing only 3 terminals, the forth hole being a blank. Don't know how to put the image up on here though ....

 

Ok, here we go There was only about a quart of fluid left in it lol all the rest was soaked up by the road year and a half ago when it happend.

There's only the two wires for that 4 prong plug in mine. Strange that yours is different.


I've circled the two outer clips that need to be depressed in order to slide the socket out.


Then here's just a basic picture of how things look.

 

Brilliant pics, thanks a million for those - they make things a lot clearer now ! I'll get pix of the socket on mine tomorrow. Looking at the first pic, if you were to cut along the blue socket horizontally from halfway down, you would have one hole with a terminal inside it and one without. That is what I am expecting to find on mine tomorrow.

I'm also glad to see that on your 200c with the 4 holed socket, it still only has the two wires.

Yet I have the two wires, the tan/black one coming from the aldl & ecm and the purple one from the brake switch. But it seems that only one wire would actually be able to do anything if you were to insert the connector plug into the socket. It is totally weird, unless I'm missing something - I just don't understand how it can possibly function .....

The thing is , the car has been off the road for a couple of years, so I've been unable to road test the car since I soldered the new connector plug onto the cut wires.

I reckon I'm going to have to bite the bullet and drop the pan - which might not be a bad thing, as I can change the tranny fluid and see once and for all how this lock up solenoid is supposed to work.

I sometimes wish I had an '83 onwards instead of this '82 ... but it's got to be said that the previous owners of my car have got a lot to answer for !!

 

Your welcome for the pics humm, I guess this old junk transmission is still good for something lol, sure is light compared to the TH400 that's in the car now. Actually have been wanting to open it up to have a look inside for any metal shavings. The guy who built a different TH400 I had blamed me for not cleaning out the cooler lines causing a load of metal go through it. I knew with 99.99% certainty, there would be no metal found in the 200c that would have caused that. Well, I was right after finally getting to open it up Clean as a whistle with only some clutch material sludge present. I'm on my second TH400 since the first one was cursed after being fixed a few times. Had the guy do all the install work so I wouldn't get blamed for not doing something right still burnt it up 2 more times. The current one has been working flawlessly and was built by another place. Ok, sorry for rambling on lol.

Now on to yours hehe... Possibly the one terminal in your socket broke off? Be interesting to see if there's a wire dangling or is attached to the back of the socket when you drop the pan. 12 mm socket for the pan and I think it was 10 mm for the 2 bolts that hold the filter Be ready for a big mess of transmission fluid going everywhere. Best bet is to take out all but 2 bolts when dropping the pan. I usually leave one bolt, backed out a couple turns, on either side towards the front of the transmission. That's so the pan can tilt down and drain a bit causing less of a mess btw, yeah I know what you mean about having an '82... couple little goofy quarks about them non of the other years have.

 

yeh i know what it's like - getting a reconditioned / rebuilt part : you install it, it either doesn't work or last long, you take it back to the person / company you got it from who then try to blame you for either install error or an existing part in your car messing it up !! When you know that you did everything 101% correct ....

Still, I think you proved beyond doubt where all the problems lay - did you get any compensation from them / him ?


I was thinking that too, that the terminal has probably been broken off - lol, as if cutting the pronged plug off the wiring for the tcc solenoid wasn't enough , who ever didn't want the lock up solenoid working butchered the socket too - previous owners, who needs 'em !?!

I've got visions of this tcc solenoid ( or the box itself for that matter !! ) self-destructing when/if I ever get it hooked up and working again.

Well, I should know more later on today when I'm up at the car and I'll get that picture taken

 

Actually, the only thing I had to pay for, other than the original rebuild, was labor for him putting the transmission back in the car the second time around. 150 bucks and he couldn't blame me a bit He rebuilt the transmission under warranty. 2 days later it was back to him doing the same thing as before. Found a problem with a center support deal causing a pressure bleed through. That caused 1st and reverse to come on at the same time. After that was done, it drove fine for about 3 months. Then I started to loose 3rd gear and reverse. Drove it till it wouldn't back up anymore LOL which was only 4 days. On flat level ground, it would not back up with the engine at 4,000 rpm hehehe. Pulled it out, stuck the newly rebuilt TH400 in I got from a friend Now the guy wants to buy back the old TH400 to see wtf happend to it so I'm selling it to him as a core. 1st and 2nd were still working great hehe. It was strange though, my stock 200c's torque converter went belly up 1st week of April 2002. 1 year later to the week, the TH400 went belly up.

 

- Oh man , that's NOT good !!!!!! I think it's great that the guy is buying the old tranny back from you - nice one !!!
