new to forum with tranny problem

i have a db1 and my tranny is having shift problems in 1st to 2nd and speedo sputters from 0 to 35 but the problem goes away when the car warms up or driving for awhile or if i punch the gas it wont do it but speedo always dose it .Checked codes no codes any suggestions…

Horrible explanation but hmmm id say your synchros for first and second gear are worn…you probably need a new speedo-cable.

Lol
