700R4
I took the carburetor off to give it a thorough external cleaning only, just carb sprayed every thing down along with the idle bleed passage ways. used an old toothbrush to gently scrub all the throttle bores, associated passage ways, throttle plates and shafts, dog leg boosters, etc, i also snugged all the throttle body/plate and accelerator pump screws and bowl bolts, the whole unit looking good as new.
I installed the carburetor back onto the intake, torqueing down the intake carb stud nuts, hooked up the fuel and vacuum lines, but left the throttle pedal and the TV cable unattached for the time being, the auto choke was set and started the engine, i planned on tuning the carb after it finally warmed up using a vacuum guage, within five minutes of warming up, i decided to check the trans fluid level, as i touched the LOKAR dipstick handle, it was hot like its been driven on the road on a summer day, not enough to burn, but hot hot, so i immediately turned the engine off, the fluid still looked normal and still smelled like new, i just changed the fluid/filter 3weeks ago, synthetic.
After hooking all the cables back up, i took it out for a test drive, even with a newly installed original GM/OEM throttle valve cable and sonnax cable corrector spring, i ditched the B&M adjustable tv cable that was installed prior, before, the 1-2 shifts always happened around 2000rpm or so, its been like that since i got the car 5months ago, the 1-2 shifts are now 2500rpm or so, an extra 500rpm bump, the 2-3 and 3-4 shifts, along with OD seem normal, thankfully.
Obviously it was my mistake not hooking everything back up befiore starting the engine, i did have a lQQk around online afterwards to get some info on if what i did could possibly hurt the transmission, all i could find is "NO, that it'll be ok to leave the tv cable unhooked just to tune the carb while idling", that made me a little feel better, but not entirely, from what i experienced with the trans fluid getting to such a high temp in a short amount of time, those kind of temps are never good on parts, regardless.
Perhaps, just from the thorough carb cleaning, the engine is seeing more fuel with no other changes and giving me that extra rpm, but that might just be wishful thinking or nieve on my part... so any of you more knowlegable transmission pros out there, what do you think, is it hurt even though it appears to be working ok for now?
Thanks
