Well I have been thinking about this ever since I had to replace my NSBU switch a couple weeks ago...

The guys that installed my SC4, well they decided that it was best to GLUE the electrical plugs into the NSBU Switch.

SO it makes me nervous as to what type of fluid they used in the tranny, its coming up on 30k miles now. So really debating on switching it over.

My question is what do you think it would cost for either Transynd or Amsoil replacement. I haven't been able to find any prices on transynd so I'm basing it off of AMSOIL.

Just seems it would be alot more for Amsoil but I don't know, that it may be somewhat hard to do a full flush if I have to buy bottles.

Will be changing both filters as well.

Thinking it would be easier to just take it to a big rig place that services Allison products and go from there.

What you guys think would be the easiest route to take?

If you contact one of the AMSOIL Dealers here on the site, I am sure we can show a cost comparison. Unfortunately AMSOIL Corporate will not allow pricing information in open form.

Also, although Torque Drive is a "Clone Fluid", reverse engineered from Transynd, it is NOT "Certified" by Allison. Why? This boils down to money, AMSOIL has done enough testing on Torque Drive to ensure quality control that they don't feel that adding the extra expense of paying Allison to Certify what they already know to be a qualified product would be cost effective for their customers. Period. It has nothing to do with the quality of the product.

Like stated above, myself included, many many people on this site and everywhere have used Torque Drive and to my knowledge there has never been an issue with any of them.

However, no matter which fluid you go with, you will have good results, you just may spend less on TD depending on what Dealer you get it from.

Alright who sells Transynd. I keep hearing of guys getting it for $30 a gallon, but all I've found is $40. I was planning on getting torque-drive because it is cheaper and I believe almost as good, at around $33 a gallon when purchasing 4-5 gal at a time. I'll check with the dealer I used to work for this weekend, but back when I was working there I thought they said it was $40 a gal my cost, maybe they said it was $40 customer cost. I still have about a gal of transynd leftover, and they would still give me dealer cost on it.

Anyway who else sells transynd, and is it typically cheaper or more expensive than Torque-drive?

They did give me a good deal on Transynd, but typically it will be more expensive than Amsoil. And the Amsoil is not TES-295 certified, but is made to meet the specs and should function the same way without problems.

I just got leery of the way amsoil said torque-drive was reverse engineered from transynd, otherwise I wouldn't have even bothered with transynd. I love Amsoil otherwise, but because they have great formulations of their own, not because they copied someone else's stuff.
