I did not build this engine and transmission, or set it up. I was watching a video from Holley about proper mounting brackets for the 700r4 TV and Detent cables.

forward to 1min, 6sec http://www.youtube.com/watch?v=HWurb3N3 ... re=related

notice the mounting bracket for the cables, and the throttle bracket. This bracket and throttle arm sets the correct position for the two cables to work with proper travel in relation to each other.

here's the setup I currently have

This looks like a OEM brackets (likely not meant for a 700r4?). The two cables are attached on the normal Holley throttle bracket locations, which places the TV cable a little farther forward than the correct Holley bracket shown in the video.

... so, is this okay?
the transmission seems to shift well and has held up to 4 years of drag racing abuse... what could go wrong if I don't correct this bracket situation?

it's hard to tell without measurements...
but from the video, under resting throttle location, the Holley bracket has the same location I do for the detent cable, but the tv cable is located higher up and farther back than mine... visually, it looks less than an inch farther back...

I don't know anything about this stuff... if the tv cable is tighter (farther forward) it causes earlier/harder shifts, and if the cable is looser (farther back) it causes slower/smoother shifts?

my shifts are pretty progressive... smooth/soft under cruising and quick/hard under full throttle. The only thing I've noticed is that it goes into over drive pretty early, like 40km/hr
... but I can't compare this to anything because this is my first OD transmission.

We just had a 200R4 rebuilt. It didn't seem to work right until the shop looked at the setup. A Holley/Edelbrock combo. They insisted we get the HLY 20-95 bracket. Welllll, it runs properly. The shop said THAT cable controls pressure. HOWEVER, 4 years of street/strip beatings, PROBABLY, should be left alone. 8)

In America we have a saying. "If it ain't broke, don't fix it." I'm not sure if they use that in Canada. But after 4 years, I think if it was gonna go bad it would have already. I'm just starting too do some research on the subject myself. I understand that the cables can be adjusted so if there is only a half inch difference in the brackets maybe it was corrected with the adjustments. Any other brackets would throw off the adjustments and cause problems. That's just my opinion.

Just to check you said overdrive kicks in @ 40km/hr so that's 25mph right? I would say check out getting those brackets b/c your overdrive shouldn't kick in till # least 40mph.

yes, if I am cruising super slow, have my foot off the gas just coasting, the stall has enough slip that she can stay in overdrive at low speeds. If I get back on the gas, she'll go back in 3rd or 2nd depending how much throttle I give it.
