water removal from auto trans

I removed the engine/trans from the old truck yesterday to take it to the carwash, the speedo gear is out of the trans(turbo 350) so its a big gaping hole there and I forgot to plug it before washing so I am pretty sure I got water in there, for all my searching I can't find a drain plug, do I remove the pan or are one of the bolts maybe a secret drain plug?

1 step forward 2 steps back around here lately

thanks

 

Goota drop the pan. Let it drip out completely. Now would be a good time to install a drain plug in the pan. Much easier to service in the future if you can drain the the fluid first. The kits are cheap and easy to install.

 

(*&$&^%$#^*()*% !!!!!!!

all that cause some **** forgot to plug the hole!!!
first auto transmission I ever had, anything I need to do while I got the pan off and welding me a big friggen plug to the bottom of the pan? I know nothing about automatics so if it beyond replacing the gasket I am gonna be lost

 

If you suspect the water got into the clutch area AT ALL or if you made the mistake of turning it over, or the water is mixed with the fluid in a milk shake looking sludge then the paper clutches may be history, and need a rebuild. I am just ****oning one up, after overhauling it on the bench in the garage, from water damage, (it was worn out too).
Take that tail housing off and dry it out well in that area too. it has an O ringseal on it so if it isn't new it will need replacing out of general principles.

Don't bother with the drain plug if it doesnt have one because you have to pull the pan anyway to change the filter when you service it.

 

A TH-350? You could PISS in it and it would still work!

I left one out behind the garage all winter cuz I thought I wouldn't use it. Turns out that in the Spring, I needed it...so I dragged it back around and bolted it up...worked fine when topped off with fresh fluid!

(Now, the little Baby Brother I've been working all day to clean up for my current project scares me...a TH-250 Metric (essentially a light duty TH-350...sorta!)!! It was CAKED with dirt and grease, and I'm sure dirt, bugs, water and other various contaminents have found their way in through the nearest convenient hole...so we'll SEE just how rugged these things are!!!)

Might need a rebuild...but we'll aim for the stars and maybe hit the gutter anyway!

 

I haven't turned it over at all yet and only suspect I got some water in it cause I took it to the car wash yesterday and didn't plug up the speedo hole, maybe only water in the tailshaft then and no real harm done?

the transmission was supposed to have been rebuilt not to long before the truck it came from was parked due to a incredible amount of rust so if I don't got to pull it apart I'd rather not, but I'd rather pull the pan and drain the fluuids rather than having problems down the road

 

Like DrJ says, pick up a new filter to stick in there while you have the pan off. Cheap insurance.

 

ok I'll scoop up a filter and pan gasket sometime next week and change that stuff out

might even slip the speedo **** back in while I'm doing that!

 

Any fluid that gets into the tail shaft housing eventually runs back into the pan.
The vavlve body is iron/steel so it can rust and stop functining.
pul the pan and let it dry out out in the noon day sun...

 

The reason for installing a drain plug is just to avoid the hot ATF douche which is inevitable when changing fluid on these boogers.I'm a mechanic by trade and its a rare day when I don't manage to make at least some mess during a ****** service. The drain kits I'm talking about involve only a hole being drilled in the pan and a self-sealing plug bolted together. Of course you are going to replace a filter as part of a ****** service. The plug just makes it a little more pleasant for the guy in the home garage who doesn't have a lift and a ****** funnel. Bob

 

Some aftermarket chrome or aluminum pans come with a drain plug already installed in them. Many are deeper than stock pans which provides extra fluid capacity as well. Some, like one my brother in law bought for his T, have hollw tubes run through them that allow air to flow through for some additional cooling effect.

Say...anyone know if TH-350 pans interchange with TH-250 pans???

(I got LOTSA ground clearance!)

 

I install drain plugs in all the automatics I have so I don't have to endure a 2nd ****** fluid bath. And the Hackster is right about those 350 turbos being stout. I bought a 79 F-100 that had a 400 pontiac and 350 turbo installed in it. I drove it for about 20,00 miles before I serviced the ****** one day. The pan was fulla MUD! I'd forgotten there had been a flood at the truck seller's place before I bought the truck from him 2 years earlier.
4 months later I hadda replace the ******. Wore out finally after towing my brother's Morris all over the midwest and running the damn thing up and down the 1/4 mile about a dozen times. Great ******s!
