It would be helpful if you disclosed a little info on your rig. Year, miles, previous and intended use (DD, offload, tow, etc).
You need to speak with the shop. But that is not a full 12 qt flush. It is a pan drop and clean (on a 200 series). Which is not a bad idea, just not usually necessary. They only have 5.5 qts in estimate. That is a "long drain" & fill or pan drop. Note: "long drain" letting transmission drain overnight will yield more. In just a quick drain of ~5 min., we get about 2.5 qts in from the 100 series.
I feel any shop that takes the time, space and capital carry cost to stock the fluid/parts for customer, needs to mark-up the prices. But $17.46 is a hefty mark-up. See market prices for: M1 MV ATF, which can be used 98-2002. Toyota IV ATF in 2003. Toyota WS ATF for 04 an u.
FIPG was used up to 2002 IIRC. After that it's a gaskets for pan to body of transmission. To my knowledge Toyota does not recommend use of FIPG on a pan gasket. Could be this shops likes to for some reason, IDK. But they do not show gasket.
I just helped a local with his 2005, do his transmission full 12 qts flush. I estimated 2 hours. It took closer to 5 hr. 5 hrs seems excessive right and it was. Well we needed too:
- Bring 05LC into shop and let cool a bit. As fill plug is next to exhaust after 2003.
- Run to parts store, to dump my catch/storage containers, to make room for ~12+ qts.
- Go by Toyota and pick up 12 qts WS ATF. Which I had to order early in week, so it be on hand.
- I had to go into my stash for washer/gasket which I spend time and money to stock.
- Set up tools along with the rig for draining, flushing and filling.
- Found the drain plug threads damaged from over torquing. Ran back to Toyota parts again for new OEM drain plug.
- Chase threads of pan drain plug hole, with a thread cleaning tool.
- Look up TSB to get new temperatures 97 to 115f, for topping procedure.
- Look up torque specs to make sure I recalled correctly. 29ft-lbf fill, 15ft-lbf check and drain plugs.
- Hook up tech-stream to see when transmission temp up to specific range 97 - 115F (TSB new range). I've tried a IR temp gun to shoot temp off pan before. I found it unreliable. It's also dependent on where I shoot beam on pan to read temp and OAT.)
- Darn if we weren't low. I've a way to make sure I've ~1/2 qts extra (more than came out) in trans at end of flush. But I'd not checked level to starts. Seems it was just a touch low. This indicates level was not set to Toyota recommend temperature in the past drain & fills or flushes.
- So now back under to pull fill plug and run fill line again, with a hot exhaust. PITA and good way to get arm burned.
- Add 1/2 qt more from my stock.
- Run up temp again and check level at check plug.
- Torque and fill & check plugs again with new washer on drain.
- Test drive, inspect and clean up.
Had we done a pan drop also, would have been more time and materials. How much time and what parts is hard to say. In our aging fleet we run into issues, especially if ever worked on before.
So again; speak with the shop!
BTW: When doing gear boxes. Let sit for 15 minutes or go for drive and let sit 5 minutes after filling, then re-top. Use new gaskets/washer and a torque wrench.
