Auto Transmission Shifting Issue Since 4bbl Upgrade

Thank you to everyone that responded with expert suggestions and opinions. After much thought over the last 24 hours, I've decided to move forward with the following plan of action:

1. Fire my mechanic who said I could simply downshift to do the same as the KD linkage
2. Order the Lokar kit (already did via Jegs)
3. Going to visit the local trans shop to inquire about a full rebuild of the A-904
4. Hope that the trans shop is knowledgeable enough to help me hook up the new Lokar kit correctly
5. Consider changing the shifter out - I don't like the aftermarket one my Pop installed. I'll seek the guidance of the trans shop on this one......
You also will need the Lokar throttle cable kit. You have to have it if you want the Lokar kickdown cable. And with the Lokar kits you won't need the Edelbrock 1481 lever/bracketmentioned earlier. I hope you can find someone who can follow instructions, or has already installed the 2 Lokar kits. It is time consuming and there is quite a bit of trial & error to get it to work right. I'd seek out a member in your area that has installed it and have him/her help you install it. It is certainly something any amateur mechanic can do. If I wasn't 900 miles away I'd help you with it!
