Uh, it BETTER say something about working in an automatic.
 Seafoam has different products for different things. What you want is 
Seafoam Trans Tune...think it'a a red and white can.
Doubt it'll help in this situation, but it can't hurt.

Subject: Follow up Re: <VV> PG no reverse and more

Here's follow up to my post from last week.  Based on the <VV> responses I 
bought a new modulator, gasket, and hose from Clark's and (after my 
unrelated medical delay this week) installed these today with mixed results. 
I'd say the modulator was part of the problem, but I obviously have more to 
do.  The fluid level is correct, checked warm, in neutral.

There is no more puff of white smoke off the line and no more engine 
knocking off the line so that's good!

However, off the line in reverse there is still a lot of slippage but after 
a good while it does grab good and I can back up, even up hill.  And off the 
line in Drive I get a very harsh vibration unless I am very light on the 
accelerator.  Off the line in 1st is no problem.  Shifting from 1st to Drive 
results in intermittent slippage and at speed I can get intermittent 
slippage under acceleration in either forward gear.

Now, I have to admit that before I consulted the <VV> brethren I did add 
some of the stuff they sell at FLAPS to seal up leaks (Lucas transmission 
fix) which is kind of viscous.  I

My thinking now is that it's time to drop the pan, clean the screen, and 
putting in fresh ATF.

I suppose another option would be to try the Seafoam since I have a full can 
handy but I'll need to drain off a little of the ATF so as not to overfill. 
(Incidentally the can doesn't say anything about using it in automatic 
transmissions which made me hesitant)

Any other sage advice is welcome.

  Yesterday I drove home my 3rd Corvair. 340 miles. Before taking the car I 
test drove it and it shifted fine, all gears seemed OK. Fluid level was OK. 
Previous owner said it has had a small leak for 10 years and all he added 
about 1 pint at the beginning of each summer. So anyway, after about 100 
miles I take a rest stop and in the parking lot on a hard right low speed, 
the PG slips. While filling the gas I checked the fluid level and it was 
about 1/2 pint low so I added a few ounces of tranny fluid. All good on the 
highway. Once near home in the neighborhood again I have slippage on a hard 
right. This all not so bad? But this morning, I start her up and I have no 
forward and no reverse. I check the ATF and the dip stick has nothing on 
it!! There is no fluid under the car on the ground. I added about 1 pint and 
I seem to have forward, but still no reverse, and I have to back it up to 
move it. So, does this make any sense? Can the tranny be that low on fluid 
and still have seemed OK? I'm thinking of just adding ATF unitl I see the 
level on the dipstick. Is this safe or do I risk overfilling?
