Dorman 65241 Transmission Oil Drain Plug Piggyback 1/2-20 Universal Fit

Beats buying an entire pan! Fit is as you make it. You need to only make the hole the minimum it needs to be to avoid leaks later, Makes draining the trans for service easier and not as messy. Functions and easy to use once installed. this is my second one on a second car.

Worked perfectly for my 4R70W transmission pan. Recommend using Permatex at washer and pan meeting points and thread sealer. DO NOT OVER TIGHTEN. No leaks, 4L60E trans pan is next.

If you have ever changed your transmission fluid / filter you know that for some unknown but obviously sadistic reason, the vast majority of car manufactures do not have a drain plug in the transmission pan like they do for the engine. So no matter how careful you are, when you separate that transmission pan from the seal the gasket has created, you get a sloppy mess with transmission fluid spilling out multiple sides of the pan top and unless you're doing this with a large enough catch pan up close to the transmission pan, you always get a mess. Well this was my first transmission service on my current truck but I plan on keeping it for a whle so I figured it would be my first and last mess! I looked around and goofed on one trans pan with an installed drain plug as well as everything else running around $300 for their "aftermarket" pans. I'm not afraid to spend money on my truck but I could not see that yet so I figured I'd pay $6.81 for this drain plug kit and give it a try. No you're going to also need some RTV sealant (just to be sure) of no leaks because we are talking about $2,000 for a new transmission so call it a total cost of around $12 for both. The biggest thing to remember is internal clearance. If you make sure the internal nut is snug and then measure from the bottom of that nut to the top of the drain spout and you get a measurement of about 3/4 of an inch height for the plug. Then look at the bottom of your transmission and see if you have a good choice for a location where there is some room and using something straight like a metal ruler, take a depth measurement by measuring from the flat surface where you bolt the transmission pan down to that float metal ruler and record the measurement. Now get a good reference point for that same location in the transmission pan and measure the depth of the pan and record that measurement. Now you do a little simple math and subtract the first measurement (protrusion depth of the transmission) from the depth of the transmission pan at the same location. If you still have at 3/4inch or more of space left over, the plug should fit with no problems. If you do not, “shop around” for another location and repeat the measurements until you find a location with enough space. Once you’ve found your sweet spot, mark it on the transmission pan and drill your 1/2inch diameter hole in it. Remember that you’re drilling through the equivalent of sheet metal so once the bit starts to go through, it is highly likely that your bit is going to catch and try to break your wrist so be careful. Now use a metal file to smooth the area and remove all burrs and then set the pan on a flat metal surface and use a hammer to lightly “beat” around the hole to make sure it is level as the drill bit may have slightly bent the pan. Now take the securing nut and both plastic washers off. If you’re going to use RTV like I did then put a small bead on the metal of the drain plug, lay the first plastic washer on that and then lay another thin bead of RTV on top of that plastic washer and insert it through the transmission pan. Now repeat the RTV process on the inside surface on the pan and then the second plastic washer. Now screw on the securing nut and finger tighten it following the RTC instructions with a drying period before you tighten it down for the final time. There is no torque listed for the plug but think of it like a spark plug, you want it tight but you don’t want to completely crush the plastic washers and squeeze out all of the RTV you just laid down to seal it. If you can let it cure for the full time listed on the RTV and then you’re good to go with a transmission pan that does not create a mess. This was a pretty easy install and I’ll still be looking but after I put everything back together and drove the truck about 10 miles, everything is still clean with no leaks. I highly recommend this product.

It's a drain plug, I've installed a handful of similar ones but this design isn't great. The drain plug bolt itself seals with an oring that does not have a boss to contain it. If you undertighten it, it leaks. If you overtighten it, the o-ring bunches up and it leaks. Replace that oring with a nylon washer and it will seal just fine. They should just include that from the beginning. The main body seals with nylon washers, they should seal the bolt with the same strategy. I would buy a different item next time.

Nice and easy to install.

Simple but effective Trans Pan Drain Plug. A couple things that make it perfect 1) Deburr the 1/2 hole you drill in the pan. 2) Use Blue Loctite Medium Thread Lock-this will prevent the larger plug portion from becoming lose. Make sure you also use a 3/4 wrench to hold the large portion from becoming loose when you loosen the 7/6" plug to drain. Make sure threads are clean and dry. Apply and tighten them very snung. No need to worry about cracking the plastic washers Why?? because you purchased: 3) Also purchase DORMAN Part# 097-021CD-rubber/steel 1/2'" oil pan gaskets. Toss the plastic washers. This way, once you apply the blue medium thread lock-you can really snug the plug up as it should be. Use a reg length 3/8 drive ratchet/3/4 deep on the inside nut, and wrench on the outside. Snug very tight-but don't over do it. Should be good! Ed.Also don't over tighten the smaller drain plug bolt/w rubber o-ring. Snug-but don't over do it.

Zero issues with it. Didn’t check dimensions before ordering just knew I wanted to install one and it’s got a decent low profile both inside and out. It’s not meant to drain all the fluid but will bring it down to a very manageable level.

Followed instructions and it leaks. Installed lock tight on inside nut, let it dry, it was tight, and leaked 1 week later. Nylon washers might have deformed from heat. Buy something better or get washers with o-rings built in.

Delivery was great and looks fine. Easy to instal. No fluid installed yet to see if it seals but I'm sure it will. I regular oil plug flat washer seal may be better than an O ring but it sholud work out ok.

Before installing I threw away the white plastic washers and replaced with much better 2 x brass washers. Same size as the engine oil plug. I also applied red thread lock glue on the threads and washers. Then installed. I also removed the inner bolt (plug) and installed blue thread lock glue on its threads. Seems to work great. Only time will tell....

Decent quality

Perfect for transmission pans. I weld these in on both sides and toss out the plastic washers. Torqure for little plug is 97inch pounds or 8ftlbs

Worked as it should
