[TR] A-type to J-type !

Yes, keep the relay.  That takes load off of your ignition switch and eliminates the need to remove and rewire all that.

 

You could move the top cover from you’re A type setup to your new J -type setup and retain all the switches.  I have that on my J-type and I have 2nd-3rd-4th OD.

Gentlemen ~

 

My A-type transmission (which was installed in my '74 TR6 when I got it, many years ago), bit the dust. I have now swapped it out for a rebuilt J-type from John Esposito at Quantum Mechanics. Though the "new" transmission is now installed (with necessary modifications to the rear mounting bracket) mechanically, I have a few questions.  I am wondering if anyone else has changed from an A-type to a J-type. Among my questions is: Since the J-type uses no overdrive relay, what does one do with the wires that are presently connected to the OD relay my A-type needed? Also, since the A-type functions in 2nd, 3rd and fourth and the J-type only in 3rd and fourth, what happens with the "extra" wires at the interlock switches there?

 

Yes, I have Dan Masters' book... His section on Overdrives is very brief (pages 99 and 100) and doesn't really mention swapping out procedures.

 

Any help/insights on these and any other differences I may yet encounter that anyone can offer would be greatly appreciated.
