Welcome!
For now, lets address the transmission
AOD has 14 pan bolts w/ P-R-N-(D)-D-1 shifter pattern, note, OD is actually a (D) .
C6 has 17 pan bolts; P-R-N-D-2-1, shifter pattern.
Assuming its the C6;
Vacuum Modulator on passenger side of transmission; Check for vacuum at mod. Should be around 16 - 21 psi in idle.
Pull vac line off,if there is a flow of trans fluid, replace modulator.
Low fluid level
Shift linkage; Purl="

Vacuum Modulator Replacement in an 89; "..The different color bands indicate the diameter of the rubber diaphragm inside the modulator. The two COMMON colors from auto parts suppliers are PURPLE and GREEN. These are for CARS. TRUCKS like OURS REQUIRE the BLACK banded modulator, likely from a transmission shop or dealer. This is regarding the mid/late 80's models, maybe more... Id venture to say any C6 with a slip in modulator. Again, PURPLE and GREEN are NOT the correct units to use, BLACK is the intended modulator as was designed for TRUCKS; by MyFullSize (Andrew)
