Well as of now I'm stranded. Help on the way. I lost D and 3rd. 1 and 2 are fine? Is it possible to be something simple? Can really do a roadside fluid check. Temp warning did come on quickly after it started slipping. We pulled over immediately. Is this going to drain my upgrade budget.

 

Bummer, sounds like a classic fail of the 3/4 clutch pack. I always limp home in 2nd about 40mph. It's only about a $100 part but probably $1000+ labor.

 

Its NOT GOING TO BE CHEAP LABOR WISE!!

You could purchase a already bullet proof tranny and install it at home. Then turn you old trans in as a core. That will get you back on the road the fastest.

Contact Rick Kim http://www.rkt56.com/ He will give you many options and help you decide the best route to take. Give him a call and discuss the options.

Excellent people and products!

One of the best trans shops in the upstate of SC said they'd rebuild it completely with upgraded converter for $2200-2500.00 and installed. They build a lot of race trannys and come highly recommended. I don't have the garage with a lift, I will let you know.

 

Its probably not a race / drag C5 but,, there are some L460 trans up-grades that should ALWAYS be done when you have service accomplished. If ALL of the issues discussed in this video below are not addressed by your shop,, you could very soon be BACK in the shop again for more trans FUN!

Here is what causes most of the L460 trans issues:


This vid details how to get the most out of your up grades and what parts to get so it doesn't happen again. Discuss this with your shop and see HOW MUCH MORE your service will cost you and if they will even do it:

Here is another video that discusses ALL the parts that get replaced and things the repair shop should know to replace. It may cost you extra cash to get some of the parts but, it worth it IMHO.


Get ya some IMPROVED AC DELCO parts:


EVEN BETTER Sun shell parts:


So,, now your armed with a little extra knowledge on WHY your trans failed and what you need to make sure that the shop does to get you back on the road and keep you there.

Another note of recommendation. You will have the Torque tube out or very close to it. I STRONGLY RECOMMEND that you have the rubber couplers inside the Torque Tube replaced with some new OEM GM RUBBER COUPLERS! EVERY C5 Automatic that I have serviced have had seriously deteriorated couplers just waiting to POP.

Its not that difficult of a job and shouldn't cost much more as the drive train is already being serviced.
