Transmission Drip?

Recommended Posts

Hi Guys,

 

Took the car out of the garage after being stored for a long while.

 

Noticed some reddish fluid on the floor under the gearbox. Only about the size of a 1p coin.

 

Anything obvious to check as i haven't really had the chance to get underneath it? There is no physical drip on the box itself that i could see from afar so it appears to be a very slow leak of some sorts.

 

The car will be going to SRD soon so just want to advise what to check

 

TIA

The oil seal can weep on the gearbox. As long as it's not pissing out it'll probably be OK for a while. I understand it's a gearbox-off job to change it though, so maybe wait until the clutch needs doing too. Or give Stuart Sandy a call and he can check it properly and tell you what's what (he's local to you).

 

Also, are you sure it's oil rather than coolant? Might the heater matrix pipes leak and drip down to that area of the car?

Thanks guys, noted - will have to get the car up on the jacks at the weekend then and have a look at the different areas it could be coming from as it wasn't clear from popping my head under.

 

Good shout to check the heater matrix pipes.

 

Problem with a small drip (1 penny size over about 5/6 months) is that it's hard to actually see where it's coming from as it's so gradual, but i'll check anything for a bit of moisture

Compare the fluid to the fluid in the coolant expansion tank, to verify if it's the gearbox oil?

 

If it's the gearbox oil there are a couple of seals that can go (selector seal on top rear prop joint?), I would take a look (stick your phone on video and shove it under there on a plank of wood or something!?

Could be the breather, mine has a small leak, I suspect it's the sump pan seal or what ever it is called. One day I will sort it out, but at the moment I'm not bothered with a little drip.... Lol. I do keep an eye on the levels so not worried.

As the guys above have said, could be power steering fluid or gearbox fluid. If it is gearbox fluid then chances are its the seals. If they are the original seals then they have probably become hard / worn over the last 20 odd years. I have a full set of OEM seals for the v160/161 for sale if you find out it is those leaking.

They do leak and btw toyota didnt design it...

 

Whoever designed it. Just because it does, surely that isnt part of its specification.

 

Not saying it's a problem. Just saying I dont think anything like that leaking, is part of its design
