2009+ Vibe/Matrix/Corolla Torque Specs-A/T Service

[Rhymingmechanic]

Can anyone verify torque specs for the filter and pan bolts on a 2010 U341E 4-speed automatic transaxle? The actual vehicle is a 2010 Pontiac Vibe.

I found specs for a 2010 Corolla:
Filter bolts: 8 foot-lbs (11 Nm), which works out to 96 inch-lbs.
Pan bolts: 69 inch-lbs (8 Nm)

Those figures came from a Chilton's database, and are the same for both the U341E and U250E. I'd like to verify the numbers, because I know aftermarket manuals are not above the occasional error, and I see very different figures tossed out for 2008 and earlier models on a Vibe forum.

Finally, my pan gasket is ATP's black fiber type. The instructions on the box are general, not model specific, and they say to torque the pan to 100-120 inch-lb. Should I use the spec from the gasket maker, or the manufacturer? My hunch is to go model-specific. The bolts look smaller than others I've worked on, namely GM TH400 and 4L60E/700R4.

Thanks in advance for your help.

Alldata says 71 inch lbs for pan, 97 inch lbs for filter. This is for FWD 4speed auto.

Thank you! Those are close enough to my numbers that one or the other should work.

And yes, the car is FWD 1.8, 4speed auto.

On the Yaris U340 I serviced, all I did was I flushed 11 quarts of Toyota WS fluid through the transmission with no pan drop. The fluid had was original with 92k on it. However, the fluid turned purple after about a week, so I wonder if there's a bunch of sludge in there.

let us know what you find about the filter, whether it's a screen or paper.

The replacement filter, at least, has the thick felt-type media.

I read--probably here--that WS gets dark quickly. Mine was really dark when I first drained the pan at 29,000, and also had a lot of gray material in it.

Finished. That was probably the easiest automatic trans service I have ever done. (Anybody who decides a transmission pan doesn't need a drain plug should be drop kicked.) I even did this one on gravel.

The filter was a felt media type, black plastic on top and metal on the bottom. It was a Filtran, made in USA. The replacement was an ATP from Taiwan. It has a wide plastic inlet with an O-ring, and does not stay in the trans during installation--It has to be held in place while the bolts are put in. I was a little nervous, because the old one did stay in after the bolts were removed. The trans shifts fine, sounds fine, and doesn't foam the fluid, so I guess I did it right.

Both magnets had the expected gray fuzz and some shiny slivers, but there was not the pile of sludge and glitter that I'm used to seeing in automatic pans. The original gasket was cork.

I would say used Toyota WS is raspberry colored. It is darker and more purplish than other fluids, which are bright red to pinkish. I had done three drain and fills of 2.6 quarts each before this pan drop, so a good percentage was fresh.

Thanks again for the torque specs, beast3300.
