Leaking transmission lines, a little help?

[Recoil Rob]

I finally got around to putting the front wheel son ramps and lokking underneath my 97 SR5 with the engine running.

There are two metal lines running forward from the left side of the transmission, the upper line is leaking where it goes into the rubber hose which connects to the radiator. Can I just cut this line back and extend the rubber hose?

Any easy wasy to get at this? It's up front, lot of stuff there. I can pull the front wheel but it's behind the wheel well. Any advice?

Also, there is a fitting on the transmission pan that connects to a hose, what is that for if the two metal ones above it are to and from the radiator?


thanks, RR

Is the black pipe on the pan itself for the dipstick?

Measure the lengths of rubber hose and go buy the same 3/8" ID hose from the parts store. Then re-install using worm gear hose clamps. The factory clamps will be too loose. The OEM hose has a bigger OD. The off the shelf hose is usually smaller 5/16" or 11/32". You can use that but it will be a narrower hose adding resistance to oil flow.

When you tighten the new clamps, the trick is to bed them into the hose so that you do not feel a ridge between the two. Too loose and it will leak. too tight and the clamp can cut the new rubber hose. Then recheck in a couple of weeks.

Note: buy only transmission hose. The chemicals in trans fluid will rot fuel hose.

I really like the factory style constant tension (spring clamps) but unfortunately Drcoffee is right, the stock clamps usually don't work with the generic auto parts store hose. I would recommend a fuel injection clamp over a worm clamp. I have have had better luck with those not destroying the hose as quickly.

While replacing lines nows a great time to add that B&M tranny cooler and never worry about the pink milkshake.

x2 on the b&m transmission cooler.

The B&M is on order and I was also thinking of dropping the pan to change the filter, it's at 137K miles. Good idea? recommendations for a filter? OEM or does someone make a better option for less $?


thanks,

Rob

This is what I don't understand about Toyota owners?? Everyone loves Toyota because they are well built and last forever. But when something on their Toyota does need replaced or fixed, they want to buy the cheapest Chinese part to fix them! Most of the time the part ends up not lasting anywhere near as long as the original Toyota part did...or not fitting at all.

Thus, most of the time, you would end up saving money and time if you just bite the bullet up front and buy original Toyota parts!

You do not need to change the transmission filter because it does not have one!

The transmission has only a metal screen to prevent large debri from being recirculated. A more aggressive filter will only reduce fluid flow into the trans. If you want to add a filter, install a Magenfine inline filter. $15 on eBay and it has a magnet, paper filter element and safety bypass valve. Rather than filtering fluid being sucked into the transmission, it will filter the fluid exiting under pressure. If the crud doesn't get back to the pan it can't be recirculated. So much easier to change every 30,000 miles as well.

Yeah I figured out a long time ago you save more money by buying quality anything. Skimp out on name brand clothes and exspensive toilet paper if you really wanna save.
