You can try calling Dynotech to see if they can help you out. I heard nothing but good things about those guys.

In addition to a rebuild, they can probably do some Sonnax updates and install a portion of the Transgo Shift Kit.

No such animal exists...valvebodies are the same between non-hd and hd.

But...I hear the Sonnax updates are well woth looking into

I believe the only things that are different between HD- and non-HD trans are the diff cover and the diff itself. There is some speculation as to casting material differences in the cases as well, but....I don't think there is any real hard evidence to back that up.

I also do not think that there are any performance-oriented clutch/steel sets. If you want a performance transmission, you use a shift-kit during the rebuild (you can actually do part of the shift kit while the trans is still in the car), but the largest rework is in the valvebody.

You WILL want and or need to replace the reverse reaction drum, and the 4th gear shaft. I am looking into possibly another upgrade, but I need to verify a few things before I let everyone know about it.

In my somewhat limited experience, I have found that the most widely available new hardparts are the improved designs, made from higher quality materials. So yes, using those hardparts will strenghthen the trans to a degree. There was also changes that were made to the 4t60e from year-to-year...some drastic, some subtle.

To give you an idea...I just built up a replacement for my car. It uses a '93 case, '95 Riviera internals, an aluminum structural side pan (as opposed to the stock stamped steel pan), and a 4t-65e oil pump cover (and if anyone is wondering...it has been verified that the -65 oil pump will bolt onto the -60e valve body, but there is an issue that I am trying to look into to make it work), and the stock '93 internal harness and temp switch. I'll be building another one up real soon for another member, though it won't be quite so Frankensteinish.
