Transmission Pan Constant Leak

That has to be frustrating, like you say a slight seeping shouldnt hurt nothing.. just keep a check on the level.

 

Very much so, I’m curious how other trucks with dropped pans look as far as any seep at a close look being that resealing a pan must be done INCREDIBLY tedious and precise to ensure proper seal.
But yeah, I will probably just keep an eye as I have a year of Toyota honoring their work and when it’s finally wet enough looking prolly mention it...
Biggest thing is frustration and money and still not 100% right.

 

I saw the pic with the Toyota Fip box, the box in your hand says camshaft housing. The Fip inside the tube is black. The black fip WILL not seal tranny fluid. Depending on which route you take with the pan, make sure whoever replaces or attpts another reseal to use the ORANGE Toyota Fip. It is specifically designed for the trans pan, and also other drivetrain uses.

 

One more thing, do not use a cork or rubber gasket, just the orange Fip. Make sure all surfaces are dry and clean, let sit as long as possible before adding fluid.

 

Sealer on mine is red, and should be correct per Toyota dealer and packing states for transmission. Dealer did the job the 4th time, already saw a rubber gasket used on the truck when I first bought it, first time this job was done shop used a cork gasket. The last 3 times a gasket maker was used and still no complete success. Out of those 3 RTV was used and 2 including the most recent one, the correct Toyota FIPG for transmission.
I really think other people’s pans have to have a seap if they have dropped it and it’s this technical. To lay the gasketmaker correctly.

 

Yours is a 2wd, correct?

 

Yep 2wd Prerunner

 

Ok. Did a little more research. Your transmission does use a gasket (4wds use fip) the torque for the bolts is very low, 39 in.lbs, which is also 3.25 ft.lbs. If the bolts for the pan were over-torqued, the gasket itself can split, causing your leak. Also, another thing to consider is a leak from above, say the extension housing, that is misleading you.

 

I haven’t Hurd anyone say prerunner actually uses a gasket? Is that straight from a 99 service manual?
And I am pretty darn sure it’s from the pan as everything is really wiped down even on top, and it’s not wet in top, just at rear seems you can see the fluid in the crack
Front is dry as a bone like when I first got the truck back from the dealer

 

Yep, straight from 99 repair manual

 

Well, I have no idea what is right, apparently service manual though if that’s really it I would imagine dealer would do that but they didn’t recommend a regular gasket. I really don’t know
I didn’t realize such a small thing couldn’t be sealed up right over $1k later, blows my mind.
What if I needed a head gasket job. Can’t have something like that leaking.

 

That is definitely straight out of the repair manual. But in theory you shouldn't have had to pay each time, "ever since" are the 2 magic words in dealing with shops. "Ever since you guys did my trans pan, it is still leaking"..
Any good shop should stand behind their work.

 

trans pan should not be this damn difficult. Shouldn't even require that much work to bend a pan out of true.

 

It's not. It's a very cut and dry repair.

 

Sucks this been such a issue. For my 2.4 taco I just bought a oem trans gasket straight from the dealer for 10-20 bucks and that worked perfectly fine. Was easy to do and really not that much room for error besides over torquing and breaking a nut.

If I was in your shoes I just up and do it myself perhaps getting a whole new pan after checking the old one for damage. Perhaps theres some gouged metal on the lip of the pan besides the previous bending, or the mounting surface wasn't properly cleaned up.

Either way though it sucks this has been such a hassle.

 

Well unfortunatly I went to a previous shop since i thought they could easily handle. So i blew a bunch there. If i go back to dealer, this we be the second time for them trying. And they'll probably suggest another NEW pan like the last shop... +$200

So one would think...

Thing is I already payed for a new pan the other shop messed up and im for certain if these mechanics with a lift cant get it right, i most definitly wont 1st shot. And me being stuburn, i refuse to pay this much and now end up doing it myself, just not having it
Plus fluid is $$$

I will probably just send it back to dealer and have them go at it a second time as now it's covered by them.
Just a pain and time consuming, and afraid theyll say i should get another new pan for THEM to start fresh
Putting me towards somehwere around $1200+
^unreal that this is gonna take 5 trys to MAYBE have it sealed shut completely
I feel im almost around what an entire new tranny would cost, while this one has 230k already

 

Part of me thinks this is all going according to plans with how much they're charging you haha. Ugh, reason why I ended up learning to wrench was for similar issues with dealers. Best of luck, as this is a terrible way to start a new year for sure.

 

Technically, this has been an unsolved issue for over a year, but now I been trying to just get it fixed for good.
I work on most my stuff that I can handle for this same reason, but more technical things like timing belt I have coming up as well is too much for me.
Most NORMAL people would never look under their truck the first time and then years down the road wonder why the transmission is shot. Well it leaked everything out and they never knew it was all due to a shop who touched it.
I check everything after work and ALWAYS find things not done right so I dread when something breaks and I can’t handle doing it myself or have the time/space.

 

I'll rephrase, it shouldn't take much effort to remove the trans oil pan, how is it even possible to bend one out of shape. I dropped the pan on my 1st gen and didn't even ding it. Had to order new bolts thought cuz I was snapping them.

 

These are pics underneath about 1k from dealer. First got it back everything was bone dry. Now if you look close you can clearly see the wet looking oil on the gasket inbetween pan and transmission and the pan edges are wet looking again from the seem sealing
