Torque specs/Capacities AT Transmission Pan
Needing to swap out the gasket in our 2000 I30T auto trans pan. Does anyone know the amount of fluid needed to put back into the transmission after I've drained it? Also, what are the torque specs for the 21 bolts holding the pan to the transmission? Couldn't find the exact info online, hoping someone has done this to their car and know what it takes. Thanks!

The pan bolts should be tightened to 61-78 in-lb.
Fluid capacity is 10 quarts. Remember, though, that simply draining the fluid will still leave some (probably a few quarts) in the system. The torque converter particularly will retain maybe a couple quarts of fluid. Really, the best way to be sure you're filling it correctly is to just fill a quart at a time and keep an eye on the dipstick.You might also consider taking the car to a shop with a transmission fluid exchanger machine. These machines run fluid through the trans continuously and will FULLY exchange ALL fluid in the trans. You can usually have this done for about $100.
For a lot more useful info, check out the transmission section of the FSM. Specifically, you should find pages 288 and 382 useful.

That should be 61-78 inch-lbs. About 6 ft-lbs. Really just need to be gently snugged, if you don't have a 1/4-in drive torque wrench.MinisterofDOOM wrote:The pan bolts should be tightened to 61-78 ft-lb.
Overtightening these bolts tends to strip the threads. Also the FSM recommends replacing the bolts with new ones - about $1 each from a dealer. They have an orange anaerobic sealant on the threads.
Draining and dropping the pan will empty out about 6 quarts of ATF. Measure it after you drain it out.

Yes, you're right. Thanks for catching that. Typing "ft-lb" must be a force of habit I guess.

Re: Torque specs/Capacities AT Transmission Pan (MinisterofDOOM)
Thank you guys for the info. We did the gasket and tightened to 70 inch lbs. and everything seems to be just fine. I think we actually put in 6 new quarts of fluids too, so right on there too. Thanks again for the information, I can always count on you nice folks here. Didn't do the bolts, hopefully never have to worry about those.
