| | | | Rebuild you 4l80e, replace the ecm, diagnose wiring problems, all for | $1750. Not bad if they did it right. Price a gm goodwrench tranny and | labor for installing it.

About two years ago, G.M. increased the warranty coverage for factory remanufactured transmissions (SERTA's) to 3 years or 100,000 miles. Most SERTA's for 4L60Es are about $2500.00 plus tax.
And, the G.M. warranty is nation wide. Not that you didn't get a great rebuild from someone you trust, but you won't get any consideration if you're 2,000 miles away on vacation and the transmission happens to malfunction.
You could easily spend every penny saved at the independent if a shift solenoid decides that it's time for retirement while out of reach of the local mechanic.
When using a SERTA, every part inside the unit is new - only the case is reused. You don't get all new parts when yours is rebuilt. Only the failed parts are replaced. Something worth a considerable value when your personal time is wasted while waiting for a problem to be looked at a second time.
Just my 2¢.
