Hello all

[Petros]

i put some seal conditioner in my trans, the shift lever shaft seal was dripping. Not that hard to replace but I had to track down the seal and wanted the dripping to stop (topping up the trans is a PIA on these cars). It is manual trans stop leak, only cost about $8 as I recall, I put in half a bottle, and it worked. A year later it has not leaked. maybe someday I will get to that seal....

This is reassuring that you, one of the more celebrated members here would admonish the use of a magic potion!
Happen to remember the brand you used?

[Petros]

I think the brand was CD3 or something like that (not sure now). There are a number of brands, you just have to make sure that is is for a manual transmission with gear oil (not ATF or engine oil). they all work the same way, they soften and swell the existing seal chemically. I would never do it in a trans with good seals, so at best it is a stop gap measure. And it does not always work, but it is worth a try.

Yea I did some reading on them and I don't quite fancy the idea of an eventuality of replacing multiple seals, as a precaution for the next day or so I dumped a little more of my old oil in.
I've got to pay my insurance or they'll drop me and my employer ain't had but 13 hours work for me in the last two weeks.

Trying to get a fix on the input shaft oil seal with the site search function is like trying to find a dingbat in a fustercluck.
This oil seal came out of the tranny I put in my little tercel, I'm using it as a template to order as many as I can get my greasy little hands on for the cheapest, from whoever.

It says KOYO CR 27 MHSA 66 48 7XRT. So variants of these character google up anything, when I replaced the oil seals in my motorhome axel hubs I had no problem aside from them being $15 per from advancedauto.com but these were beefy HD 10 ton truck axel oil seals and are still in use today in light duty delivery trucks.
I know y'all be gettin some oil seals for the main inputs, who has em?

Did you try a Search in the Forum Talk forum? see this thread from there and you shall find the answer: https://tercel4wd.com/forums/viewtopic.php? ... 702#p57702
Try it - our site is not the only one where this magic is required.
If you think it could be from the CV seals, see https://tercel4wd.com/forums/viewtopic.php?f=16&t=6484

No I'm pretty sure its from inside the bell housing, the diff shelf is a puddle zone, then it runs down the driverside, but it also is getting down the exhaust line somehow, uphill from where it puddles and on the other side of the bell.

Think I found it

When you mention "diff shelf," do you mean the plastic panel which is supposed to be a guard, extending from below the radiator rearwards?
If so - you have something that most of us do not!
See https://tercel4wd.com/forums/viewtopic.php? ... ane#p72018
I'd sure like to find one - as well as the panel that fills the gap left when the AC condenser is not installed.

Oh my no, I wish, though I bet I could graft the one from my blazer on, but I think the blazer needs it, I would actualy do that kind of thing to the blazer; high center or nose dive it this little toyota feels as fragile as carnival glass.

I mean the shelf that the design of the front differential creates, driver side of the differential top is lower that passenger side, so when the main input shaft oil seal leaks it comes to rest on that area its just strange that its making its way uphill around the passenger side of the bellhousing and onto the exhaust line.

Wow thanks hendrix

I had a thought, double clutching on acceleration? harmful, frivolous or beneficial to gearclusters?
I'm not talking double clutching on a deceleration snap revving the accelerator between gears, I mean just tooling along through accelerating ranges.
I tried it today on my way to the grocery store and it seemed to far lessen the feelings of the gears and synchs through the shifter.
I can forgo a clutch, I don't want to waste this transmission though. I guess I'm just paranoid though.

[irowiki]

When both of my manual transmission tercel's are cold sometimes I have to double clutch on both up and down shifting for some gears. I don't do anything fancy, just clutch in/out/in then shift to my desired gear. The problem usually clears up by the time it is hot.

[dlb]

i was reading about double clutching a while ago and my understanding of the technique is

1) stepping on the clutch,
2) taking the shifter out of gear and leaving it in the neutral position,
3) letting the clutch pedal all the way up,
4) stepping on it again,
5) and then putting it into the next gear.

i never really knew what people meant by double clutching but apparently the key is letting the clutch up with the shifter in neutral before trying to get to the next gear. i also read that semi trucks need to do it because their transmissions don't have synchros, apparently. i still don't totally understand how it aids shifting in their case, or with conventional transmissions though.

[irowiki]

It helps trucks shift precisely because they don't have syncros!

Yea I read up on it when I got home after doing it on the way home - no real mention if its upshifting, but wiki has definitive identified it as a downshifting method; also the heel-toe method, witch I'm sure we've all done to limp a vehicle home with a standard transmission that has trouble keeping running. I had a 79 chevy luv that lost gen/alt in the end, it would die unless you kept it gassed just above 1000 RPM, I had to master that technique real quick.
