5R55S auto transmission. Has about 60k on it, was rebuilt less than 2k miles ago. Trans worked great until it lost 4th gear recently, may be as simple as replacing the solenoid block (avail. pretty cheap on eBay) which was not replaced during the rebuild. Would be a good deal as a possible cheap fix, or great for somebody looking for an extra unit for a built transmission. Looking to sell locally (SO Cal). Asking $350.

 

BUMP... This thing is wasting space, price is now $250.

 

What transmission do you have now?

 

$120? Somebody take it!

 

So, this trans was rebuilt and now 4th gear failed. Why was it rebuilt in the first place?

 

this is for gt right?

 

Yes, its for a GT. The transmission was rebuilt due to a broken input shaft.
