,,"~ ---, l,et1ter SERIES 300 TllANSMISSIONS _IIJ -,,-, bygo rg Rihl Having rbuilt hundrds of th cast iron and aluminum transmissions through th yars, I hav.. found many ar not th originals that cam with 300 as it lft th n~ctory. During th car's lif, a transmission woulduail th for on rason or anothr. pormany ownrs that had transmission problms during th warranty p~:riod, Chryslr dalrships would mak rpairs or install, in... 1rm cass, a rplacmnt unit. Whn th car was out of warranty, (\ local transmission shop would b slctd. Many of Ilhs shops would hav a "rbuilt" unit on th shlf Bcaus all th transmissions lookd th sam physically on th outsid, many tims th rplacmnt unit cam orilginally from a Dodg, Plymouth, DSoto, Imprial or non-300 Chryslr and Dodg truck. 1 hav found that through th y:ars, approximatly 10% wr original 300 transinissions, and th fat that whn an original 300transmissioll was rbuilt, th propr job was not don according to what th factory spcifid.. That is, many \vr rbuilt to (II "normal" transmission. In othr words, closr tolrancs, pf()pr~lmounts of friction and stl discs, band adjustmnts, rar clutch (low gar) spring, govrnor and lin prssurs wr not rbuih or rplacd according to Chryslr l1\cl:ory spcifications. Ths srvic bulltins \vr not availabl to transmission shops. Th "'rbl1ilt"/"rplacmn " transmissions did noilalways hold up and gnrally did go bad just ovlr th war~anty priod. This mad many 300 ownrs unhappy with thir "Chryslr" transmissiion. I prsonally had this silllcltion on my 1957 300C. Within on month in 1963, a slmlp had to go through it thr tims. Th third tim it wnt bad, within 5 mils, I told thm. to contact my local Chryslr dalr. Thy got th corrct information and th transmission has workd as it should. During th tim] was rstoring my 1961 3000 coup and my 1960.300F, I was concrnd if my tmnsmissions Not: 10 arly 1959, th shift cabl was th sam as '56-'58 TorquHit and had thr pic valv bodis.
