I don't show a 2CR code.
Hopefully someone has it.

 

I'll go out and check. it again . .this time with glasses

 

Well the code is right.

CR F
284-862CRF1172

 

I didn't say you read it wrong ,just not in the list I have.

 

Looks like a 86 Monte or GP:

CRF 85-88 LG4 305 powered Monte Carlos/Pont Gr Prix

 

That's what I first thought.
'86 Monte (w/305)is 6CR.
Along that line ,the 85 (w/305) is 5CR and the 86(w/305) is 6CR.
'87 GP(w/305) is 7CC and '88 GP(w/305) is 8CC.

 

Thanks , guys

I checked with chevy and they think the (F) means 85 . Just wanted to know if this is a good trans to install in my 1971 Chevelle

 

The 'F' started in 86 -denotes 200-4R.
