5R110 pan bolt torque spec

[tech10002]

I'm getting ready to change my fluid, internal, and external tranny filters. Does anyone know what I should torque the pan bolts to? And is there any specific torque sequence?

I'd be very interested in this as well...being that I'm due for a fluid change.

And I'd prefer not to take it to the dealer.

Anybody, anybody??? LOL I snugged them all up, but I don't want to go too tight for fear of warping the pan. Then again, I'd rather not have the pan fall off in the road too.

I don't believe thier is a Torque sequence. The bolts should be torqed from 12 to 16 ftlbs, if it were me I would go 12 ftlbs, I learned the hard way and went with 16ftlbs and ended up having to use a couple of Hela coils. The Transmission housing is Aluminum and the threads are very brittle.

I just talked to a tech. He said 11 foot pounds on the 5R110 and 12-16 for the 4R100. I think I will play it safe and go for 11. I just snugged them up earlier and drove it 50 miles or so. It didn't leak, so it obviously doesn't need to be too tight.

Since there are several people ready to change their fluid/filters too, I will post my experience.

I pulled the drain plug with a 13mm end wrench. I used a 5 gallon bucket to drain into and it was approximately half full when it stopped draining. You need a 10mm socket to remove the pan bolts. A universal will help with the ones above the cross member. Remove all the bots but one on the front and back. Remove the last two carefully and drop the pan straight down since there will still be a quart of fluid or so in it. Pull the internal filter straight down. The little orange rubber gasket stayed in place on mine. I got it out with a small flat head screwdriver. Just be careful not to nick the bore it installs in. Lube the orange seal on the new filter with tranny fluid and push it all the way up. Clean the pan mating surface on the underside of the tranny with a rag and clean the pan out too. Make sure you remove the magnet and get all the metal shavings off it. Clean the pan gasket with a rag and then reinstall the pan. Run all the bolts up finger tight and then work your way around snugging them up. Finish up by torquing the bolts to 132 inch pounds with an inch pound torque wrench.

To change the external filter, place a catch basin under the filter housing and loosen it with a 22mm socket. It is located near the front bumper just ahead of the passenger front tire. Spin the housing free and grab the filter and pull it down. You will lose a small amount of fluid. There is a spring loaded retainer on the bottom that might fall and hit you in the head, so be careful. Don't ask me how I know this. LOL Pull the old filter off and then push the spring retainer back in the new filter and push the filter onto the tit on the top of the filter mount. Then screw the housing back and tighten it.

It took exactly 10 quarts to fill mine back up to the line on the dipstick. The fill location/dipstick is located on the passenger side of the motor near the A/C blower box. It will appear overfilled when you first check it, but once you drive it, it should be right at the top of the "hot" mark on the dip stick.

Take it for what it's worth since I'm no expert.
