subarubrat Posted November 22, 2016 Share Posted November 22, 2016 I always wanted to do an SVX project and it looks like one may be coming my way. The master plan is two swap in either the V10 out of the BMW M5 (clearance permitting) or the Chevy LSA 6.2ltr and a Tremec TR-6060 trans. Both a similar in baseline HP and potential. I am going to look at the candidate car later in the week. Like many SVXs it has a failed 4EAT, not a big deal as I plan to gut it, and the history of why it fails (overheating too much weight) is well known. But I am curious, when they fail do they hard fail, slip allot, stop shifting, etc. just what do they do? The thing is going into the recycle bin, but I am curious what SVX owners have seen.

golucky66 Posted November 22, 2016 Share Posted November 22, 2016 Typicality, It's an issue with 4th gear and lock up. Some combination of that is the most common issue that you'll see. Link to comment Share on other sites More sharing options...
subarubrat Posted November 22, 2016 Author Share Posted November 22, 2016 Cool, thanks, just trying to get a heads up on how much trouble it will be to get this thing home if it is a no rust candidate, trailer, flatbed, etc. -Another candidate engine on the table I forgot to mention is the Ford 5ltr Coyote, height wise it might be a tight squeeze even with a tube frame x-member but it is on the table. I am going to stash the EG33 away in case I come across an XT chassis, I am itching to redo my original SVX into XT swap, with today's transmissions and engine management it should be light years ahead of the original version.

crazyhorse001 Posted November 22, 2016 Share Posted November 22, 2016 Typical failure is a loss of 3rd and 4th gear. It will still go under its own power up to 50mph. If the cooling system is good, a 50-75mi trip on side roads should be doable. Link to comment Share on other sites More sharing options...
Numbchux Posted November 22, 2016 Share Posted November 22, 2016 Yep, the one I had had no 4th gear. When you got going fast enough to try to shift into 4th gear, it would just free rev like it was in neutral. Pull it down into 3rd, and it was good to go.

Yep and it will do that for about 200-300mi, then 3rd gear will evaporate....can ya tell i've been there, and proudly wear the t-shirt?
