700R4 valve body gasket supplier

[90Supurban]

I am trying to put my trans back together on the '90 burb and apparently the GM gasket kit #08689949, is only shipping with the case side gasket. It is supposed to have both gaskets. First, I received one from RockAuto like this. Then I called Summitracing, they actually went out and checked their warehouse and found the same issue. I don't know how long they have been shipping like this.

Is there a GOOD aftermarket alternative? Since RockAuto is selling the set for about $6.50, there does not seem to be much incentive for anyone else to make their own gaskets. I do not want to wait for GM to get inventory or fix their shipping problem.

Call Transpartswarehouse.com and let them know what you need; specify auxiliary valve body so they know what gaskets to sell you.

TPWH is located near Redding, CA and usually ship within a day of order being placed. I’ve been buying parts from them for 15 years, no issues.
