alrighty... soo... its been awhile since i've posted here.... hope u guys can help me as much as you did last time.

well my transmission was slippin or something, so i checked fluid level and it was fine... thought maybe i should drain the fluid, fill it back up... change some gaskets (it had a bit of a leak)

so i take the pan off.... and drain fluid... and in the bottom of the pan ... what do i find.... well idk exactly but it appears to be a spring.... a couple green plastic pieces... and a bent up piece of metal.

first one's just the parts laid out on a tissue, second has a quarter for size comparison

oh yea almost forgot specs:

1987 cadillac brougham d'elegance 5.0L v8 RWD
83k miles (i think... it could be 183k... theres only 5 digits in the odometer)

so i guess my question would be.... should i just get a new transmission.... can i fix this one.... are they unimportant parts.... (probley not)

any help is appreciated

I think that green plastic gear is the speedometer gear. I could be wrong, but I will google and see what I can find. Nothing that holds a load would be plastic. They are differnent colours for different rear gear ratios and tire heights. Don't stop worrying yet, just hope I'm right:thumbsup:

Ok, I can't find any specific pics of that piece. I think I am right, but here is what I would do. Go to a transmission shop, and ask one of the techs what it is. Tell them what it is out of (TH700R4). They should know right away. If it is a speedo gear, they likely have them, or can get them for you.

alright, will do.... theres a transmission shop right up the street....

but are you sure its the 700r4? i thought the 1987 brougham had the thm200-4r?

also could this cause it not to shift and whatnot? i would imagine so.....

I love a challenge.

Take a look at this PDF file, it has an exploded view of every part in the trans. Find the one that you took out (I think it is #171), then you can figure out what you need.

TH700R4 parts (http://www.racetransmissions.com/catalogs/TH700R4partsCat_MonsterTransDotCom.pdf)

Hope this helps,

I figured it out. It is called the trans part near the rear with green plastic. Like someone else said, it is the gear for the odometer. You might have lucked out, except for some slipping.

If it is slipping, you do not want to drive car on freeway for any length of time, as tranny will overheat from slippage.

Crap, is it a 200? I thought the 307s got 700s. Hang on, I'll go look up the 200.

Got it. It's a green 10 tooth drive gear in your 200-R4. They have them in stock at this place:

thanks a bunch

have you ever used that specific site before...? just want to make sure its reliable

or alternatively would there be a place locally that would stock that kind of part?

I'd check with a local shop - they might have the part right on the shelf. Stop by the dealer, too - they will be able to at least give you the part number, then you can check it online from places like gmpartsdirect.com. Also, try Napa, etc. It looks like that website sells a lot on ebay, too, so you should be good to go with them if you can't get it local.

They have the one you need on ebay (not the one in the pic):

One more thing: after replacing that part, make SURE you adjust the TV cable correctly. Hopefully, that is why the trans isn't shifting properly. Also, make sure you have the correct amount of fluid in there, too. The wrong amount will screw up the shifts, too.

alrighty.... sooo.... went to the NAPA parts store, and they werent open....

so i went to pep boys (yea im not too fond of them but it was next door)

and one of the guys knew what he was talking about for once

he said yea it is a speed gear, and the spring is apparently from the valve body, so im not entirely sure that getting just that parts going to fix my problem....

gonna talk to a guy i know at a transmission shop when theyre open 2morro.

alright been awhile

ordered the part online, installed it, put transmission fluid into it

only problem im having now is the TV cable adjustment

in my haynes book it says its either in the engine or by the accelerator pedal.

well im 95% sure mine is by the accelerator pedal, but i have no clue how to adjust it.... it looks like the automatic adjusting one pictured, but i dont c any adjust tab or anything.... and i also have no idea what the other one would look like

anybody have any guides or anything on how to do it?

Looked at this post a little late - just fyi, I have used both www.transmissionpartsusa.com and www.bulkpart.com many times with good results.

Every TV cable adustment that I have seen is done where the cable attaches to the bracket by the carb or throttle body. There is a metal clip that you pull out in order to allow the cable to be adjusted - once you pull the clip the cable will sort of loosen. You then mash on the gas pedal (engine off!) all the way to the floor in order for the cable to self-adjust. It has a rachet mechanism where the cable attaches to the bracket that sets the adjustment. You can modify the shifting a bit by pulling the cable up an additional notch after doing the pedal adjustment. Kinda hard to explain on-line, look up some Google info on TV adjustment, you will see what I mean.
