The 6.99 is the correct one for the t-case though, as you mentioned (the name matches the tsb exactly) - i just thought it odd they would have the same pn. I’m glad you posted this - I was planning to buy fluids today. So now will be ACDelco DEX VI for the ol trans and the 6.99 MTF & TC for the t-case. Thanks again!
