Sorry if I failed to use the search function properly but I haven't seen a whole lot online about this. I run over to an AMCOO yesterday while my fiancée was in a store and asked if they could correct a leak for me and got a counseling session from the manager. So I know I have a leak currently at the transmission cooling line connection on the bottom driver side of my radiator. It leaks while the truck is running and under pressure. I had tightened it up a little when I discovered it to be the culprit (of the front end leak) and figured I needed to disassemble it and put some thread tape on it and it would be good again. AMCOO did their customary diagnosis for their fee, ignored the front and told me a had a bigger, even huge issue with a leak at the manual shift linkage on my transmission. My truck is 1992 F150 5.8L E4OD, 4WD W/ locking hubs and 4x4 shifter in the floor, 142K. They gave me their quote to drop the pan, change the filter, replace the manual linkage seal, and fill. They also warned that I should address this leak soon due to the amount of burnt fluid and mud/debris all up and down that side of my transmission.*

First off. Are there any write ups or how to videos I should look at if I care to attempt this seal replacement myself?.

Second. How urgent does this really sound? After driving my truck home, I noticed a lot more red fluid up at the front on top of my lower radiator hose than I did poking my finger along the top of my transmission fluid pan (found a little). I know I have leaks at the front seal (engine has been resealed and regasketed (including the rear main)) and at the back of the trans to the transfer case. With all repairs requiring time and money (with the main drawback being my truck is my daily for the next month due to some personal on goings) I had been monitoring my tans fluid levels and never seen it low (I think I have added an 1/8th of a quart of fluid to it over 10K since I've owned it. I had noticed and known about the amount of debris on the right side on my transmission and assumed with the way engine was leaking oil prior to being worked that was the main culprit. I think this weekend I will Gunk everything and power wash so I can look for fresh fluid. Note: The transmission fluid is bright red (I think the PO had told me he had replaced it) and the transmission has always shifted fine thus far.*

If it is uncommon for this repair to be super urgent my plan would be to drop my truck off in December or so to give my buddy a month to remove, reseal, and reinstall the transmission (about $250 plus parts). With work conflicting with my possible Deer season this year I doubt I'll put 5K on it between now and then.

As long as you keep the trans full of fluid, you can let a leak go as long as you can stand it. It's not under pressure so it cannot blow the fluid out rapidly on you.

BTW the correct name for that seal is the shift shaft seal.

 

 

 

i would take it to a local auto repair shop recommended by friends and family before letting amcoo touch it. they are out to make money off you which is evident by the fact they want to repair something you did not ask them to, and disregarded the repair you wanted done.
the shift shaft seal is probably not even leaking enough to warrant fixing.

 

a friend of mine took his chevy truck on to amcoo because it wasn't shifting and they told him it needed rebuilding for 2500 bucks he couldn't afford that so he brought it home and we was standing around bull****ing and i happened to look underneath and noticed the vacuum line was off the modulator i told him to buy a new modulator and a short piece of vacuum line took less than a minute to install and shifts fine now all for a pepsi and a kiss from his girlfriend.

 

Hence I am asking about the parts on rockauto. Looks like something I can do myself, and while I have it drained I would thread seal the leak at the radiator. Also I want to add the dorman drain pan off amazon wiht the drain plug while I am getting covered in the mess laying on the ground.

 

Sorry, they called it a manual shift linkage on the repair quote.

 

bump for attention, I would like to go ahead and order the seals.

 

how do i take the linkage out of my c6 to change the seal.

 

There was a youtube from AutoResto Mod for the C6 I think.
