Yea I didnt want to ever have to preform this swap but my T2 is in sad shape. And I found a 90 GXL for a good price and its in near mint shape. After I get all my parts together I plan on a full T2 swap with a Haltech E6X.

 

friend and I did the auto to manual thing PITB..don't forget to swap the speedo cable also..the auto and 5 sp have diffrent toothe counts. so using the auto in the 5 sp you will be a little off on the MPH.

 

i didnt swap the cable and mine is just as off as it was before. The tooth count wont matter for the speed, if the cable turns it will turn the same speed either way.

 

Can you switch 88 rx7 convertible 5 speed transmission to a 6 speed transmission.

 

Here's some good info:
