Wagon drives now! Took about 4 weekends to get the stock auto shifter to play nice with the 4L60 but now it selects all of the gears and they line up with the positions on the shifter in the cabin really well. Reverse lights are running of the adjustable switch inside the auto shifter housing too, instead of the PCM. Using the stock shifter was a personal requirement, just not a big fan of the Hurst type shifters in a stock interior.
All door cards have been removed and fish oil injected into all the doors. Silicon spray into the window channels and all of the mechanisms greased - Really makes a difference when you don't have to fight the windows up and down!
Car is booked in for a new windscreen this Wednesday, and an exhaust on Thursday. Will be going with a 92 240 windscreen without the chrome and a 2.5inch quiet exhaust.
I found it difficult to locate a grommet on eBay for the PCM but found that a regular sink plug from Big W worked a treat! Just drilled out the center, added a slit in the bottom to slid it over the harness and it looks great IMO. The hole I drilled was 52mm so I could get the connectors run through and the sink plug is 50mm... close enough!
