Tranny Shop Houston / Dallas

Did you get the solenoids upgraded when you did the sc? This increases your line pressure and prevents your bands from slipping. If you take it to the dealer they charge around $400-$500 for it. They replace your factory solenoids wth corvette solenoids. I think parts are around $150. Should help. Good luck

no, I don't know enough about transmissions to say anything definite, but it reminds me of a transmission on its way out.

The engines in the h2's are indestructable the tranny's not so much. You might wanna consider getting the solenoids and see what happens. It might give you some more time before you need a rebuild. If you do need a rebuild it might be your bands. Either way you might want to think about that upgrade it'll help your tranny out alot.

Sounds like your band is burnt. This happens a lot on SC H2's. You need beef up the trans with a better band and clutches, shift kit, and bump the shift pressures with a tune. Not quite sure, but maybe even a corvette servo also if the H2 doesn't already have one.

Get servo from Vette that is same year model as H2. Chevy dealer vette only guy I went to school with says it should do the job nicely. He mentioned going to non computer controlled vacuum regulator to get line pressure. He said it would especially 2005 and up that went to hardened sun gear cage and to 5 gears rather than in previous year models 4 gears hold up nicely under SC situation.
