am swapping my 98 gt 4r70w automatic transmission. I did my research and learned that only another 98 gt 4r70w automatic transmission would be an easy plug-and-play fit. I took my transmission out and bought a transmission from a guy who owned a shop 4 hours away. The guy told me it's a 100% plug-and-play as it is another 98 gt 4r70w. However, I think it's a Mercury Grand Marquis 4r70w transmission. The wiring harness for the transmission is completely different and when I looked up the numbers located on the wiring harness of the transmission I bought (4w7t-7c078-aa) it came up with a 03-04 Mercury Grand Marquis Town Car Transmission wiring harness. My 98 gt transmission wiring harness is much longer than the supposedly 98 gt transmission wiring harness.
My question is can this swap still work? Thank you for any help.
