Re: IML: 1960 torqueflite question

[PAUL WENTINK <randalpark@xxxxxxx>]

There should be fluid running through the lines. Before adding an 
external cooler, I would want to know why there was no fluid in the 
lines. The radiator cooler will work fine if the fluid reaches it, so 
at this point, I would not bypass it yet. As long as the fluid is clean 
there has been no damage so far. That could change quickly on a long 
drive on a hot day.

The external cooler is a good idea to prevent ruining the transmission 
should the engine overheat. I have had this happen on another brand of 
car, where a good running engine that simply ran on the hot side all 
the time ruined the transmission while the engine remained top notch. 
In that case, I believe that the built in transmission cooler was 
inadequate to begin with.

This problem is not inherent to a 1960 Imperial. I suspect blocked or 
kinked lines. Get underneath and do a visual. The trouble should be 
easy to spot. If not, you may have to do some digging.

Subject: IML: 1960 torqueflite question


Hi List, 
 
Last month I pulled the radiator of my car to have it re-cored. So far, 
so good. The radiator is like new again but something is worrying me.. 
 
When I unscrewed the cooler lines from the radiator I noticed that no 
ATF was dripping out. I also expected a flood of oil coming from the 
cooler unit on the radiator but nope.. 
 
Ofcourse I am aware that this could be a dangerous situation for my 
tranny! 
Heat is one of the biggest enemies I am sure. 
So what could be wrong here? 
 
There is almost no dripping from the cooler lines while they are 
hanging free now (maybe that is logical, cause the engine isn't running 
so no pressure will be built up). 
Ofcourse the cooler lines could be blocked, that would be the most 
obvious reason. As soon as the weather permits I will remove those 
cooler lines from the tranny and I will clean them out then with 
solvent and airpressure. 
 
But if the lines are open, what other options do I have to check for? 
On the repair pages of our website I noticed that member Philippe 
mentioned that when you have cold oil cooler lines (and thus no oil is 
flowing through those lines) the regulator or the converter valve 
might be stucked. 
Philippe was talking about a 57 torqueflite, does this also makes sense 
for a 60 torqueflite? 
 
Btw, the tranny is still shifting perfectly through all gears, nice 
gentle shifts (but not too soft) that only are getting a little firmer 
when the engine and tranny are at operating temperature. 
The shifts are smoother with a cold engine, what could be explained by 
the fact that no oil is flowing through the oil cooler. The oil is 
clean, pink, and smelling fresh btwn (not burned). 
 
Any thoughts what might be wrong here? 
 
Thanks, 
 
Robert
