Transfer case/transmission seal...

[cruisermatt]

If you run that hose with the automatic transmission you will have serious trouble on your hands.

Gear oil =/= Automatic Transmission Fluid (ATF).

 

[Lasse]

Yeah. Thats why you only does it on a car with a proper transmission
It is a standard M18 plug on both transmission and transfer. Go to any hardware store and get M18 single high banjo fittings and M18 banjo to 1/2" or 3/8" hose barb fitting and some tube rated for oil/gearoil and you are set. Cheap and you are only doing thia as a temporary fix. This is by no mean a permanent fix so why cash out for a bling, bling fansy stainless solution?
Oh. Remeber to use copper washers!

Lasse, for a lot of us the hose is indeed a 'permanent' fix. It's more than a band aid, it solves the issue once and for all. I've had mine on my 40 for a decade. With the hose on there it neutralizes the pressure from the Tranny and the t- case. And the one Shipmag sells is a very nice one at a fair price.

Now with that said, I do agree with you...if you are getting inside the tranny or t-case for some other reason...do the seal.
But the hose is a good & proper fix until you get in there.

Can't install a tranny to t-case hose on an auto tranny, no fill plug as on the manual tranny.

 

[cruisermatt]

There is a fill plug and it is the same size as the manual transmission, but this is irrelevant as this hose shouldn't be used with the a440f transmission, but it would install.

 

[shipmag]

SOR sells the kit that connects the fill hole on the tranny to the fill hole on the transfer. Roughly $100 IIRC. It works, but the fittings are a bit leaky and its too long IMHO. I can snap some pics if you'd like

Id like to see pics please. I think there are things about the SOR version I don't care for

Did you ever do something about getting a hose. I am putting together a group buy for the FJ60 crowd. The couple I have sold to guys with FJ60 have been 17.5 because thats what size I had. If I do a buy I can get any length you decide you need. The 17.5 is $61.00 unless the vendor increases the price at time of order with him. Here is a pic of the rig a guy sent me for an FJ60. He installed a 17.5 hose shown below. I do not own a FJ60 so the length is up to you. You will have to measure it. Send a pm for paypal instructions for $61.00 if shipping in the USA. Other wise pm me for shipping cost. The $

61 includes shipping.

Hoses will be in Friday according to UPS. To those that have purchased them I will be sending them out on Friday. I have ordered a couple extra 12.75 and 17.5 lengths to accomidate the new customers of the FJ60's

 

[shipmag]

I have hoses both sizes in stock ready to ship pm me for paypal instructions.

In the next week or so I will be ordering some more hoses. I do have both sizes in stock now.

If you need a size other than the stock sizes of 12.75” and 17.5” Center of Banjo bolt to center of Banjo Bolt, now would be a good time to order. If you order a non standard size alone my vendor charges almost double. If you have a non stock set up and want these teflon heat resistant hoses with a Stainless Steel braided outer sleeve please do it with this order.

PM me if your interested.

Use a rope or electric extension cord so its stays rigid. Measure center of plug to center of plug. The standard for Toyota plugs on transmission and transfer case is M18x1.5. If yours is a pipe thread youll have to get an adapter as banjo bolts are not made in pipe threads because of the taper of the thread. Ebay has the 1/2 pipe to M18x1.5 adaptors.

Not sure if a PO retapped your plug holes? Hold a straight edge to the side of your plug if its has an angle its pipe.

PM if you have questions. Ive seen a lot of different things PO’s have done and can help you figure a solution.

Ive sold over 400 hoses to cruiser heads. Yep replacing seal is the fix. But did the guy rebuilding your case put the case back together with grooves in the shaft from where the seal rides? The hose is just cheap insurance and the stainless steel braided hose resist the heat from the exhaust pipe that runs close to the hose.

I have just received a new shipment of hoses. I have both sizes in stock now. If interested PM me.

If you get the truck high enough off the ground you can sit up under it and dissemble the t-case with everything still attached. I didn't pull the transmission when I did mine. You can rebuild the whole thing if you want or you can fix just the leak. I think with the manual you should be able to fix it on a Saturday. Don't forget you will need all the gaskets for the t-case, it comes off in layers, not heavy either.

My 88 62 had Oil coming in on the interior instrument cluster

figured it was gear oil

I lowered the amount of oil

but it looks like transfer case is leaking into trans

Without rebuilding - what would a shop reasonably charge to fix the seal between the transfer case and trans ?

I just want to make sure no more oil comes into the interior

thanks

You could probably replace the speedometer cable or maybe just the o-rings to fix the leak into the cluster. But why do you think your transfer is leaking into your transmission? If you have an automatic transmission the two boxes use different types of fluid: transmission fluid vs. gear oil. I don't think you want the two to mix, especially on the transmission side.

To replace the seal between the transmission and transfer case, the transfer case has to be disassembled. Your mechanic would need a gasket/seal kit, then he would clean the gasket surfaces and put it back together. I'm never paid someone to do this, but it could be like 10 to 15 hour labor, plus the kit? I'm sure someone will correct me.

While he is in there you should also have him check the transfer case vent to make sure it is not blocked. Oil creeping up the speedometer cable seems like the transfer case might be pressurizing due to a blocked vent.

After you go to all the trouble, expense and effort to finally replace that seal, just know that not too many years in the future that new seal will wear and start leaking again.

In 1989 I installed a new H55F transmission in my FJ60 and rebuilt the transfer case with new seals and everything.
It couldn't have been more than 3-4 years after that, that I started detecting oil migration.... the seal was leaking.

Not wanting to deal with replacing the seal again, I just kept a regular eye on the oil levels for the next 25 years. Adjusting as needed. Recently, I had the time, garage, second car and equipment (transmission jack) to deal with it. If I did not have those things, I never would have replaced that seal again and just kept on top of the oil levels for as long as I owned the car.

My new transfer oil seal does not leak now. A few years in the future? I am sure it will.

This is where it pays to use a GL4/GL5 oil when you're running a manual since it's compatible with both gearboxes. I'm a fan of Red Line MT90.

Frankly I'm surprised no one's produced a longer lasting, more reliable seal for this application. Seems to be a weak link in the 60 series & earlier drivetrain.

Edit, just realized how old this thread is. Dang.

Thank you for the response.

When my friend removed the fill plug for me, red ATF fluid came out of it. Oil is a mixture of gear oil and red ATF.

My question is, now that we lowered the fluid level, and if I start driving it again, I don't know how quickly transfer case is migrating with ATF, so that it will puke it up by speedometer again.

Transfer case vent seems like a good thing to check.

As in can I drive it 500 miles, or 5,000 miles, before I need to fix it.

If ATF is leaking into the transfer case then the ATF level in the transmission may drop to a level that performance is affected. You could also have gear oil migrating into the transmission and that would need to be addressed immediately otherwise you will be facing a major transmission problem.

Yeah to be honest I am not sure what is happening (as to which way the oil is migrating). I am going to drive it a bit, keep an eye on the trans fluid level. Was running perfectly fine last 10K miles, before oil smell in the interior, and oil from speedo

You can get the the transfercase vent from underneath. If my memory is right its a 25mm wrench use a box wrench and fit it between the floor and top of vent tube. Once broken loose may unscrew by hand if i remember all this right?

The transfer case breather is a press fit into the top of the case. At least on my FJ60, it is difficult to get to while the transfer case is installed in the truck. If you remove the transmission mount, holding the transmission/transfer with a jack, you might be able to drop it enough to access it. When I had my transfer case out for resealing, I replaced the press in breather with a threaded elbow and ran an breather hose up into the engine compartment.
