as the title says, what is the ultrabell part number for a B/RB to A518/46RH/46RE ? i'm having trouble google searching for this. summit's site isn't too clear [at least to my old brain]. part # 92457 ? if not that number, what is it ? anyone out there have one ? TIA as always !

Yep, 92457.

I always wondered, if you have to use an ultrabell anyway is it worth using the 518, or just go with a 4l60 or something else?

thanks john ! your summit link was way more descriptive than the summit link i viewed. thanks again !

I am putting a 48re behind one....

another question i forgot to ask about the 518. what year was the last for the mechanical speedometer output ? or are there outputs on some of the RE transmissions that can be converted over ? again, TIA.

I think '97...in '98 the speedo sensor moved to the rear end.

thanks again john !

Are you installing an Ultrabell onto the 48RE?

The best transmission I have ever owned and driven is an Extreme Automatics built 200R4 with a Precision of New Hampton 3800 stall, lock-up, billet converter bolted to my 408 Magnum with a Reid bell housing. They can be built to handle up to 1000 hp & 800ft lbs of torque, are more efficient and are compact. I didn't have to cut my floor either.
