So what you're saying, Deathrat, is that no Bonnies from 92 - 95 used the HD version, supercharged or not?

The HD transaxle was used in an entirely different car (in this case a caddy) and never in a Bonnie. (?) And the pan on my trans that reads 4T60E should not have 'HD' on it (I was under the impression that the previous owner of my bonnie swapped the HD for a standard - but from what I'm reading here that wouldn't be the case.)

Gordy...help settle this. How many planetaries were in your diff when it exploded?

Maybe I should explain better.....
The 92 SSEi'* (or any other Series I for that matter) never got the HD. There was no HD version of the 4T60-E that went into a Bonneville! There was a HD version of the 4T65-E though for the Series II'*. It could be possible to "custom" build a HD version of the 4T60-E though as Ty has done with his "Bullet Proof" Transaxles, but outside of that, a Transaxle swap would have to be done from another car line. The only "STOCK" differences between the SE, SSE & SSEi'* were the Final Drive Ratios. Hope this helps.

hi

is it possible to swap out a 4t65e for a hd version for my 1997 LSS n/a ?

Please try to start a new post instead of digging one up from the 'archives'

Yes, it is. Direct bolt. You may have trouble matching gear ratios, though. The HD is 2.97.

hi

then its a matter of a pcm flash. it seems that since these pcm'* are rather primative computers with the processing power of a 486 pc, one could write code for them once he has the source code.

i'll look into this.

"archives" lol.....this thread was last posted to only a little over a month ago.

That'* old
The point is that people have to read through 2 pages of an old post to get to your new question.

hi

ok, i understand, not a problem.

i post frequently at pc tech sites where threads can be hundreds of posts long and can span 2 or more years one thread i can recall spanned several generations of chipsets and cpu technology.
