Thread: Start motor without Trans T/V cable?

Tweet

Just installed the 700r4 but don't have the T/V cable. Can I start the engine without damaging the tranny? I don't plan on moving the car or revving the engine. I just want to know if the tranny will go into the gears at low speed and the rear wheels are off the ground.

Could do damage. The tv cable adjust the pressure in the trans. I am no expert ,dont know for sure.

700R4's damage easily if that cable is not on and adjusted properly,do yourself a favor BUY the cable first! Go to google for tips on adjustment of the cable also not a bad idea to have a trans shop make the final settings with a pressure gauge.

It won't hurt a thing. One of the reference measures when setting up a 700R4 is to determine the pressures in ALL gears, at idle and with the TV disconnected. Don't wing the engine or drive the car, though.

No offense, but I'll repeat my disagreement. The manufacturer of my 700R4 (Bow Tie Overdrives) not only said it was OK, they said it was REQUIRED to measure the pressure in every gear with the TV cable disconnected as a part of the set-up procedure.

How else do you top off the trans fluid, which includes moving the selector through the gears to fill up all the servos, and valves in the valve body, cooler, and lines ???

yeah and watch the tranny fluid pour out the tv cable hole put a drain pan under the passenger side of it if you do so after all what do i know i would just buy the dang cable your going to need it anyways

And after you drain the wine bottle to keep the contents from going bad, you wont even care

(Sorry Denny, I just couldn't pass that entry up )

you can buy one from $20.00 - $30.00 at napa

I started and left at idle speed (500-700rpm), went through gears ok. Plugged cable hole with piece of vacuum hose and looped cooling lines. I did this because I did not have mounting brackets for throttle and TV cables yet. But the bowtie overdrive website recommends doing this test for pressures.
Thanks for the help.............
