Burnt Fluid

hi all, i've been chasing leaks in my '65 falcon c4. while i had the pan off to change the gasketi also changed the the shift lever to vertical to accommodate a locar floor shifter. i've been meaningto do this for years. of course i had the valve body out to do this. everything went back together asusual.and because i couldn't leave well enough alone, i adjusted the bands when i replaced the locknuts on the adjuster screws. i followed the ROM procedure: torqued to 120 "/lbs. then backed off the intermediate band 1 3/4 turns and the low reverse band 3 turns.i suppose i may have gotten this backwards: front band 3 turns and rear band 1 3/4 turns.would this account for my burnt fluid? or is it likely something else?the transmission seemed to shift and drive fine until i noticed the burnt fluid smell.and of course the tranny also drove and shifted fine until i started all this. thanks.

Re: Burnt Fluid

That is a pretty loose adjustment . Doubt it would burn the oil.
Usually front band a max of 1.5 out , quite common in some setups to go one turn or just over . That's with a coarse thread , fine thread is different

Rear is usually 2--2.5 out .

Re: Burnt Fluid

hi gregaust. and if i got it backwards and only backed the rear adjuster out 1 3/4 turns, would that be enough to toast he rear band?

Re: Burnt Fluid

I doubt it . I have set some 2 to 2-1/4 turns out and no problems

What line pressure did you have ? What type of cooler? What lines ? What valvebody? Is the modulator connected ?

Was the oil ok prior to this band adjustment when you had the valvebody out or is this just recent that the oil is burnt?

Re: Burnt Fluid

unfortunately, i don't know what the line pressure is, no gauge. the cooler, lines and modulator are stock.the trans has a TCI converter and a Performance Automaticvalve body. it's been in this configuration for several years and worked well until i tried to adjust the bands. and at that time the fluid looked new.yesterday i backed off the adjuster lock nuts and ran the adjuster screws back in, torqued to 120 "/lbs and counted the turns required.i got approx 1 3/4 turns on the front and 3 1/4 on the rear. so assuming my old craftsman torque wrench isn't wildly off i didn't get it backwardsand they weren't to tight.i'm tempted to just refill with new fluid and see what happens.thanks

Re: Burnt Fluid

Run it and see I guess . Reason I asked line pressure is the rule of physics?? High pressure = high temp.
