my TC became pouros and fluid was leaching through the metal

Ugly for sure............never seen a TC that bad, but have seen a lot of rusty ones...porosity-in-the-making?

I was having a similar problem with mine. Turns out the ATF level was extremely low. Enough fluid to run flat, but not enough on a hill since the pump was sucking air. The fluid could be worn out and lost its viscosity. The reason for the low fluid, my TC became pouros and fluid was leaching through the metal. Watched the TC sweat ATF while it was on the bench in the hot sun. He should check his ATF level and condition.

sb,
    I guess there is the no cost versions and $cost versions. A stall spped test would identify the converter quick enough, but then what about if the clutch has an issue? I agree that checking the TC Bolts is an idea - but imagine the noise if they are all out? Well - the ring of machined metal around the TC would be visible anyway ;D . Other than what you have descibed - how about checking the oil pump functions? 52 PSI at idle means it may squirt,  but a line may be being choked off somewhere/somehow?

I'll let my imagination dwell a bit more - but it may be a case of up on stands and examine the Bellhousing & Clutch on the bench.

From my perspective - TC or Clutch needs a good look.

Turns out I had a bad intake leak at one of the manifold crush rings. I had some other reasons to pull the motor so its out now for some work.

Good to hear- are you now able to reset the idle speed where it is supposed to be? (About 950 at idle in neutral, usually drops to around 750-800 or so when put in gear.)

This is not my car, this is a PM I received from someone over on the samba. He has a 68 autostick where if he is stopped on a hill, and tries to move off he barely has any power at all. He says if he puts it in Drive 1 he has no power, if he puts it in Low the car barely moves forward. But any other time starting off from a stop the car is fine.
I've given him several suggestions (the obvious stuff like checking ATF level and pressure, hoses for leaks, adjusting the clutch servo arm, etc.) I have described for him how to do a stall speed test to check the torque converter but he needs a tach for that which I don't think he has.
Is it possible the flex plate has come loose and the extra power needed to pull a hill from a stop is causing to slip on the crankkshaft but on a flat surface it doesn't?
Only other things I can think of would be internal to the transmission such as slipping clutch disc, or possibly worn input shaft?
Any other ideas you all can come up with would be appreciated-thanks!

Ok, figured it out. I had recently swapped to a ribbed style alternator belt. Put the smooth one back on and the noise is gone. It may have been the wrong size and was too loose or too tight. Either way, all is well now.

Technical / Rattle at idle in gear
« Last post by aberg83 on 26 June 2020, 13:46  »
So I got my shifting working thanks to some help in another thread. Might need a slight adjustment since it still grinds a little going into reverse.

My biggest issue now is that when the car is in gear, idle rpm drops quite a bit and was initially stalling at stops. I increased the idle to around 950rpm while in gear. It is up over 1000 in neutral. When in gear, the engine doesn't sound healthy. There is some rattling going on. I suspected the torque converter because the sound is gone when in neutral. I thought maybe a flex plate bolt was loose so I checked all 4 and they are tight.

Any ideas?

You nailed it. The diaphragm in the servo had come loose from the seam. It was actually intact. I re-installed it and voila! All is well. Thanks!

Well that is a weird problem....  it must have been repaired at some time ????
I have a repair kit for the clutch servo plus 2 spares...

Yes, the previous Owner rebuilt it not long ago and swapped into onto a different transmission. While doing that, it must have been pulled loose. I made sure it is nice and tight. Works great!
