Anybody got a PN for the lower hard trans line on a Sy? Was polishing mine when I noticed that it had a rub hole darn near all the way through....

Re: Lower Trans Line part number

Just got off the phone with my parts guy. Gm took the number out of the system and just lists discontinued. I am still working on getting the number and/or locating one

Why would this be different from a regular 4.3/4l60 s-10? I could see the top one being different, but the bottom?


Thanks,

Im just relaying the info I got. I am still looking into it. But looking it up application specific sy/ty it comes up n/a.
 
Re: Lower Trans Line part number

mine had a rub hole in it too that the tranny guy found when they took it out, and he just spliced it with some compression connections or something. i am converting to the 80e so i just took off both of my lines. if you want me to take a pic of them i would let you have them for shipping.

its not serviced "improvise from bulk tubing" Is yours complete and uncut? I can have it made in 304 stainless if you want or you can just send it to www.inlinetube.com

It's stock down to the original GM label still on it. Only thing wrong is the rub in it.

If these are unobtainum now, might not be a bad idea to get a set to somebody to have a pattern...

Re: Lower Trans Line part number

I made new ones after the stock one in the truck in the next size bigger line since the fullsize trucks use that size and my replacement radiator had a trans cooler with the larget fittings. My stock line has no rubs but I did slice it where it bends to run up to the motor. This made it much easier to disconnect there instead of the trans for removal. Might not be a bad idea to get new ones made with this in the design.

Re: Lower Trans Line part number

I did consider fixing it... I was just hoping I didn't have to.

I have a trans cooler plumbed into this line already, and it didn't really look right plumbed into the lower line like it was, kinda flopping in the breeze. I'll probably just cut it and double flare it right where the gouge is. After looking at it, It'll probably look more 'stock' this way, and will hide the cooler hoses a bit more.

It is my attempt to keep it as stock appearing as possible, where it's practical to do that.
The only real departure from this is the chrome valve covers, although some GM cars had them. (Just not this one) I may go back to the black ones, but it looks so flat-contrast that way.

The rest is done with as close of a color match as I can find. The frame will be touched up with a zinc phosphate coating and the spray-wax stuff that the factory used. The fenderwells need to be re-done too, but I've never found the right color... it's a semi-gloss black, but it had a greenish/brownish tinge... not the same as the body color or the usual Eastwood underhood black. I may just end up hitting it with POR-15, since I can't find the exact stuff.

Otherwise, the ABS is there and intact, the stock air intake is there and will continue to be, and it'll generally look like OEM, just a bit shinier in places.
