[Gmecm] Geting rid of electronic transmission.

[Doug Chase]

Very interesting.  That contradicts what I have heard elsewhere.  I guess
the thing for me to do is to install a transmission temperature gauge.  My
reason for not doing it so far is that I was afraid of what I might learn.
;-)
 
Thank you.

Thats about the worst idea you could possibly have.  The TCC is not designed
to take the abuse of heavy loads on it.   I run about 45% TPS MAX before I
unlock the converter, especially at lower vehicle/engine speeds.  Locking up
as soon as you go into 4th, gives you a bad bog, and poor acceleration.
Fluid will still get to the cooler in 4th gear.   I have a transmission
temperature gauge.  I drove around without a functioning lockup for some
time, not knowing it.   The transmission never ran any warmer than it did
with the lockup functioning.   This is pulling a 5,300 lbs aerodynamic brick
with only a 305.

The reason the transmission guy thought it was a good idea is because when
that transmission is in 4th gear and not locked up the fluid does not flow
through the cooling circuit.

This is probably rarely a problem in town, but it can be when towing.

My Blazer briefly was wired so that TCC locked immediately in 4th gear
because the transmission guy thought it was a good idea.
