JC316 Posted February 5, 2014 Report Share Posted February 5, 2014 Hey guys, I'm new here, but not new to mechanics. I've got an 00 Silhouette, I know, not a W body, but the power train is the same, and the transmission is busted. No 4th gear, harsh shifts when hot, P1811 in the history codes on it etc. I figure that I have two options on it. One, I can go in, change the pressure solenoid, change out the 4th gear clutch hub and pray for the best. My second option is to just change the transmission with a used one, which seems like the best option since it's such a cheap tranny. My question comes in as to what the difference is between the BRB and BCB codes? I found a chart on here that shows them to be identical. Same ratios, same converter, same everything. I tried googling this info, but I haven't found anything. Most GM transmissions that I have encountered only care about the gear ratios or the TCC solenoids, but that seems to be the same on both.

Imp558 Posted February 6, 2014 Report Share Posted February 6, 2014 Hmm, there doesn't appear to be any difference. I'd fly it http://gmtuners.com/transmission/ Quote Link to comment Share on other sites More sharing options...

JC316 Posted February 7, 2014 Author Report Share Posted February 7, 2014 Thanks for the replies guys. I am pretty much at the same conclusion, it appears to be a sick joke by GM. Every piece of information that I have found shows them to be identical and interchangeable. Quote Link to comment Share on other sites More sharing options...
