02 jetta limp mode
 

Hello new to the forums, and sorta new to vw's
I bought a 02 jett 2.0 160k miles, guy i bought it from said was running fine and pulled up to a light going to work and was in limp mode and its stuck in 3rd limp mode, i ran the snapon soulis scanner on it came back 5 codes wich will be attached to this thread all point to the tcm.. I been reading up tcm bad with these codes, its also leaking from the bellhousing, i pulled the over fill plug *on level ground* and fluid is dark not burned but a lot was coming out.. Now before i start throwing parts at this i need input, thank you for any help in advance
