tranmission problem just had it built
 

Hey guys i have a 99 dodge i just had the transmission built with triple disc converter billet input shaft valve body all new clutchs.. the problem im haven now is if i Floor it running from roll at 45 55 mph its kicks out of lock up from 4th to 3rd and redlines and seem like its not pullin like its free reving.. I called my transmission guy took it to him we test drove it he goes thats not right it shouldn;t do that he says its nothing he done he said the lock up and 4th to 3rd all computer controlled he said I needed someone to get into my ECM and tune my transmission does that sound right to you all ? and who would do that kind of tuning ???? Someone help me out cause kind of confused and need to get something done about it thanks !!

did they readjust your tv cable when they reinstalled it?

Well yeah .. it bang through the gears awesome .. like i said on here what he told me its in the ECM that lock up and 4th to 3rd all computer telling it what to do .. from what info out of him ..

nah I dont beleive that. Ive built several and never heard or seen a need to go into ecm for anything. sounds like gov. press. not set right or tv cable mis adjusted something like that

Assuming it shifted right when you drove it away from the transmission shop, I'd say probably your "transmission guy" is blowing smoke up your arse. :humm:

well dang hhmmmm Hey Miller where in Ky are you at ?? if ur close by i'll come see u and see what you think ?

I would agree with miller boys.I build transmissions and if the TV/kickdown cable is misadjusted or if the return spring has been left off can cause high throttle valve pressure. This will affect upshift timing and firmness can make it feel as if a shift kit has been installed with later upshifts. It can also cause a trans to downshift too far seeming like a neutral condition example shifting down to 2nd when it only should have downshifted to 3rd.

I know the cable is adjusted right.. Where is the Return spring at that im lookin ?

The return spring is located on the TV lever at the trans and usually attached to a bracket on the left side of the bellhousing to return the lever.

well the spring is there .. This guy has built alot of dodge's transmissions i just dont get it .
