I was reading some info on here and I believe the trans that I got form ATS is a 47rh. Just to make sure the 47rh looks like the 518a but on the passenger side it has webbing sticking out that is part of the trans case? If it is a 47rh what do I have to change to the inside of the trans to make it work with a lock up converter?

 

ATS probably used a newer case to build your A518, thats why it has the reinforcing webs on it. Internal parts are what need changing. Input shaft, front pump and cover, valve body, etc.

 

sounds like ATS just used the newer style case (47RH) and then more than likely used the non-lock up internals (valvebody, pump and input shaft) from the a518. For the most part, the tranny's are identical internally, and exteranlly, main difference were a few beefed up internal parts, which can be swapped in, and the changes needed for the lock up.

 

It dose not have a lock up converter in it now. Was toying with the idea of putting one in and wondered what was required. I know about what needs to be done externally just not internally.
Thanks for the help
