G'day everyone, long time not on here, so busy these days, hopefully some one out there can help me, I have had my 4 speed Jetaway tranny rebuilt twice now since 2013, this should not have happened, but we do cruise my caddy everywhere, last trip in 2014 was across Australia, 7500 miles, and we average 10,000 miles in her each and every year, the Jetaway is just not up to scratch, I presume there is a number out there that have done the Turbo 400 Conversion?

Mine is a 61 Cadillac deVille 6 Window Sedan, have attached updated pic, I have found one place that has an adaptor plate,  This is the link for the part I need, anyone deal with Speedway Motors?

Will need a new starter too, which they have the link on that link, so will be also needed.

Do you know any alternative to this, or should these guys be my best choice?

Regards and safe roads Milton Watkins (aka CaddyDaddy here in Australia)

HI Milt, good to hear from you again. I believe Chris Oz put one in his car and really liked it. I haven't seen him on here in a bit but you might try sending him a message anyway.

Hey there, thanks, yes I wish I had the time to read all the posts here, I love it and miss it, must come back more often.

Have had the issue resolved, give it one more chance, got freshly rebuilt 61 tranny off Tom Dean here in Australia, he'll be fitting it and rebuilding it, quite a workshop he has there, he is one of two Hydromatic specialists we have here in Australia, so its in safe hands, maybe my box was never really fixed from the start, had a vibration that I could not get rid of after the first rebuild.

So lucky I got across the Nullarbor and to have got around so far, will be nice to have a good box in the Caddy, maybe will last a long time like it should.

If this don't work I'll go the route of the Turbo 400, but let's all hope it goes well.

Thanks. Milt

I have had massive problems with this transmission. But after I have found the right guy to do it, it is unbelieveably smooth, quick and absolutely dry. The car changed hands and did not run for 20 years because of the transmission... Therefore I would consider a swap unnecessary but it is critical to find the right person to do the job. Good look! I know it is possible although I was desperate for some time.
