Help. Leaking trans. Need name of part. Sign In

I have a 1988 Cadillac Deville and its spraying trans fluid. It seems to have cracked just a bit. Like a brake line would. Its a small tube. I have no experience with this assembly since its my first car but it looks as if i could replace it myself. Heres a photo.




The big circle is the unknown assembly and the little one is where it is spraying from. Its on the drivers side. I need to know its name so i can gather some more info. I know its probably a basic part but i just dont know it.

Look like #6 ? Transmission fluid cooler pipes

Modulator is the small round looking thing above #20




Here is a pic of the modulator

Thank you so much. Im goin to the auto store in a few and this diagram is so perfect. Im pretty sure it will be an ok fix on my own. Ill ask at the store if your right but that to me looks spot on.

Probably won't find that cooler line at a parts store.
Modulators they have but not these cooler lines i don't believe.

Probably Dealer only and may be discontinued being an 88.


Stop at a GM Dealer parts dept ,or call, and see if its still available

Double J : Time to have this as your sign off...........



Original poster - you may have to make that up - dunno for sure. That or a world wide hunt but ask as Double J suggested. Forget regular parts stores for something like it IMO. Trans shop w pic maybe some help. That or once in a blue moon found myself at a plumbing supply place for stuff to make something up as it should all be NPT threads (plumbing threads) .................

With Tom on this...

IF unavailable ,have one made up.
There is a place here by me in Chicago that will make any hydraulic line you need and better than the original.
And while you wait...
There's places you can find online that can make lines exactly to spec. too.
Of course there's always the junk yard,IF you can find a good one .



Hows that Tommy? ^^^

Re: Help. Leaking trans. Need name of part. Sign In

Yeah theres a few pick yards im gonna call around too and a few tranny shops as well. Im leaning more towards the custom line though. I want to sell it and the cars in great shape just that damn line. I want to replace the brake lines as well just incase i keep the car. These damn salted roads and poor attention from the previous owner took its toll. I got the car for free so its not so big a prob if i had payed 900 for what its worth to me. We have a few cars here so i was gonna sell this and use it as a good start for a bike this summer.

Thanks for the help though i tinker but have trouble identifying names and caddilac is just a whole new world for me as i grew up with ford trucks and buicks. Lol i loved that regal.

x6rosenrot9x : Quick look aftermarket this is N/A at one only. May - dunno - be part of a whole line set. Still can be made up. You pic shows what it would look like where Double J and I live in no time if used on salted roads!

If doing this yourself you have to look hard to see if a set or separate part? Can't say. Can you do just a section if it's really good - IMO yes.

Unless you have the time and place even if a few bucks you'll find a trans shop or about any good shop should handle this.

Dealing with those flare nuts: Trust me, they will not cooperate! Slap! You cut those with snips, wire cutters or the tubing cutter if room NOT a hack saw so no filings get involved. You can frequently cut the line such that a six point socket will fit over the flare nut.

I have more bullcrap for getting rounded or rusted flare nuts like shown out from all angles, crow foot ones - probably close to a grand in just that nonsense. Think about it.

*********************************
Double J! Love your sign off! IDK - just showed up when looking for Caddy stuff out there. I'd blow a buck on something like that instead of something I could really use - laugh....... Tom

My local CARQUEST makes custom lines. If you have them in your area you may want to check there. I know all too well about the salted roads. Salt sucks!
