ACCEL CABLE DIFFERENCE
one is for aod trans 40" long E5TZ.9A758.A
other is c6 or m/t 39 5/8"long E6TZ.9A758.D
mine is a c6 but I'm wondering why the diff in cable length and part#.anyone have an idea why?
For carbureted vehicles that came matched with an AOD transmission, a throttle valve (TV) rod was used. A C6 used a kickdown rod. They look similar but are very different. Shift points on a C6 is controlled by engine vacuum, and the C6 kickdown rod only controls downshifts. In contrast, an AOD TV rod completely controls ALL shift points and kickdown functions.
To work correctly, the AOD TV rod has to follow the movement of the throttle lever on the carburetor throughout the ENTIRE RANGE of travel. Therefore, a different carburetor was used with a special throttle lever for models that used an AOD.
A TV rod can physically connect to a carburetor that has the standard kickdown throttle lever for the C6, but the AOD will not shift correctly. The AOD will burn up very fast because the TV pressure would be all wrong because the entire travel of the throttle lever would not be followed on a carburetor (and throttle lever) designed for a C6 transmission.
The different throttle levers had different locations for the accelerator cable (and transmission rod) to connect to. And that is why one is slightly longer than the other.
Capiche?

I didn't mention in my post that these #'s for the accelerator cables are for EFI engines.same #'s works up till 89.the t/body was the only piece that I didn't look up and they are different #'s .there is only one part# for the main mounting bracket on intake .I figured they were the same travel as my 95 t/body .the cable I have now was out of a 86 lariat with auto and fits perfectly.I'm assuming that lariats 5.0's were all aod not c6??. originally used the 95 cable from my parts truck and was way too long.looks like the best way is to unhook the cable I have now and measure to verify.
thanks for the help,
Andy
