I was about to change my transmission fluids and had a question about transynd prices. I was looking on the internet and on gmdieseltech.com the 5 gal. pail of transynd was $205. Do u think it would be cheaper to go through a dealer or through this website? Are the prices the same as from the dealer or is this a high price for this product? O and the 1 gal. containers are $45!!! Please need this info so I can save some money or see if this website is competitve w/ the allison dealers!!! Thanks for your time!!!
