Front Seal Retainer Housing

On a w59 manual transmission 5-speed 1996 Toyota Tacoma 2.4 is there a gasket for the front seal retainer housing?

 

No gasket, just RTV. Toyota FIPG or permatex ultra grey are recommended.

 

I didn't think there was because of all the videos I've watched and diagrams I looked at but I'm trying to find out for sure so I can get verification because I had this automotive shop replace my clutch and front and rear seals and this will be the third time I'm having to stick it back in the shop because of seal leaking thanks for responding back to my inquiry

 

Do you know where it's leaking from? If it's the input seal itself, your input shaft may be worn. There may be a repair sleeve available for it? The retainer has a nice wide sealing surface for the RTV so as long as both surfaces are clean it shouldn't have a problem sealing there.

Kwik-Sleeve™ is a fast, economical and effective way to refinish a seal-worn shaft. It is a precision engineered sleeve made of stainless steel and then hard chromed for extended life. Because of its thin-wall design, a Kwik-Sleeve can be used without changing the size of the seal and its finish is ideal for lipsealing applications. No expensive preparation or machining is required before mounting.

Each Kwik-Sleeve comes with a removable installation flange and its own installation tool. The installation tool reduces the possibility of sleeve distortion and provides for sleeve installation without the removal of the shaft from the serviced equipment.
Minimum Shaft Diameter Range 1.179"
Maximum Shaft Diameter Range 1.184"
Installation Depth 0.688"
Width On Shaft 0.315"
Overall Width 0.433"
Flange Diameter 1.4"

 

It was not leaking when I first put it in the shop, normally I would have done it myself but a situation came up such as the VA providing me the wrong orthotics for my feet causing my skeletal alignment too get out of whack resulting in a pinched nerve in my upper back and first time I pull a transmission out of a vehicle of my own I always change the front and rear seals and this is the first transmission ever had a front seal retainer housing and from what you're saying they should be putting the RTV sealant on the seal itself because the mechanic told me it wasn't leaking around the seal and I'll bet they're putting the RTV sealant around the edge of the housing I ordered a gasket set that applies to about four or five different W Transmissions and I'm waiting for it to come in so I can take it up to the automotive shop and tell them I want my transmission fixed right and I want them to go and correct that bolt they did not put in correctly it still got about 1/8 of an inch to go it's hand tight but it's not properly flush to the engine

 

The seal presses into the bearing retainer, no RTV needed you just tap it in. The perimeter of the retainer needs RTV where it mates against the transmission case, but both surfaces should be very clean.

There are aftermarket gasket kits that include a paper gasket for the retainer, but Toyota does not use a gasket.

Some possible leak points:

If some of the retainer bolts are loose then that could be a leak point if they didnt go around all the bolt holes with RTV and or the retainer is not fully pressed against the case
If the retainer mating surfaces werent clean and the RTV didnt adhere well
If the input shaft has a groove worn into it you need a repair sleeve for the seal to work properly

 

If the input shaft had a groove wore and it, wouldn't it have been leaking before I even put it in the shop? Because it wasn't leaking when I put it in the shop

 

Probably. If they forgot to tighten bolts on the retainer I would say they messed up. I attached a diagram with torque specs on my first reply if you want to print and give it to them.

 

Thank you Chris for your input and the information and I was planning on showing them all this and I was wondering are you a Certified mechanic because you seem pretty knowledgeable about this and it would be great to be able to tell them so I don't have a dispute with them and I can get my truck fixed and not be charged any extra

 

Anyway thanks for your input and the information and now I have verification that it is their fault and they need to fix it and to tell these certified mechanics at this automotive shop what they need to do to fix it

 

I am not a mechanic, but the document I attached is from the toyota factory service manual. My W59 trans recently had some bearings go out and I rebuilt it myself. Works great now with no leaks

 

thanks Chris you're like me a uncertified mechanic I just can't believe that an automotive shop wouldn't know about this because the chief mechanic and owner was telling me that he looked all over the place for a gasket and couldn't find one and that it was not leaking from the seal then when I presented to him what the Toyota dealership told me was that possibly the housing was warped or may have a crack in it because possibly they didn't torque it down correctly he said that he helped the mechanic put it on and they're supposed to be certified mechanics

 

So with your input and knowledge that possibly they cause a groove in the shaft because it was incorrectly assembled back together to begin with, at least now we know we may have to get a sleeve
