Rick, I hope I'm understanding correctly that you haven't changed the linkage,
just replaced the cable on a system that was working right before? You adjust
the throttle cable first with the TV unhooked. Then adjust the TV to fully
stroke the plunger. The plunger cannot be over stroked due too the design of
the lever that works it. The lever will bottom out against the valve body. But
I don't know any other way to be sure the plunger is fully stroked without
watching it.

Mike, I understood what you were saying about WOT. Several web pages that
I looked at just said to ensure that at WOT, the cable can not pull out
further. I assume ( we'll see where that gets me) that if the cable is fully
extended then the plunger must be at full travel. Would that be correct? I
just hate to drop the tranny pan. On the other hand I'd hate it more to burn up
the tranny.
bad66 - The TV cable adjustment is critical. If its not correct you can
burn up the tranny within just a few miles. Or so I've read on many web pages.
I was looking for info on adjusting it by the pressure readings, but Mike
reminded me of the remove the pan & visually check the plunger method.
I am concerned right now because I had the TPI system apart and want to
get the TV cable adjustment right. If you have been driving yours a while &
everything works correctly I'd say that you are close enough. Do a google
search (there is a LOT on the web) or read the links that Mike provided
earlier for better info than I can provide.

Rick, The procedure is the same for the TPI system. I didn't catch that in
your post. What is important is that you are getting WOT and that the plunger
get's fully stroked.

Thank You Dale, that should work most excellently! And Mike thanx
for the information. This is for a TPI system, not carb. But I know that
the procedure is the same, just different bracket. That info looks very
familiar, I forgot about it. I used that procedure when I first installed
the 700 with a carburetor . Messy but I know it works.

Rick, The best way to set the TV cable requires the pan off the trans.
You disconnect the TV cable at the carb, make sure the throttle is giving you
WOT. Then connect the cable and get a friend to mash the pedal to WOT. The
plunger that is activated by the TV cable needs to be fully pushed into the
valve body, basically flushed. If it is not adjust the cable tension until it
is. If you are using BTO's brackets on the carb end and a Lokar cable, this is
the basic adjustment. If you are just changing out a cable you need not worry
about any pressure settings.

Thanx Brad, but that particular post & most everything else I've
googled refer to a stock cable. There is no tab to push down with the LOKAR
cable. Its a braided cable, adjusted by movement of lock nuts at the mount
bracket.
The TV Made EZ page & its links give the procedure with a braided
cable, but not the specific pressures to look for. Bowtie OD wants you to
record the pressues, email them, and then they tell you what adjustments to
make (as far as I could find).
Late last nite I found a Swedish (I think) web site thgat gave the
pressures in KpA (??) and if I can find some type of conversion chart it may
help. Any more info will sure be appreciated. I've had great luck &
reliability with this tranny for 10 years & don't want to burn it up now.

Does anyone have instructions/advice for adjusting the TV
cable on my 700? I am using a LOKAR TV Cable & Bracket on a TPI motor, not
the stock zip & click stock cable. When I installed it several years ago, I
adjusted it using a gauge and had to read specific pressure ranges for each
gear. I can't find the info used back then. Thanx

One reference (from Corvette Forum):
The TV cable adjustment is made on the side of the carb. It is
something that can be done in a few minutes. If your pivot point is correct all
you do is push in the metal tab on the cable mount and push the nose towards
the firewall or into the mounting bracket then take the carb throttle linkage
and give it full throttle until the cable ratcheted out and the butterflies of
the carb are at full throttle position. This should adjust the TV cable
correctly. If you make the cable shorter by pushing it into the body the shifts
are alot harder You can try this but the 1st time you floor it the cable will
self adjust. I mentioned the throttle stud must be in the correct location so
that at a given throttle position the TV cable is pulled out the correct amount
for line pressure. I have these demensions but not here. The shop that rebuilt
my transmission wanted my copy for their files. Remember to adjust the TV cable
nothing but the aircleaner must come off.
