I've had a look around the forum at different diff ratios and it seems that a 3.55 centre is okay with a hydramatic. I'm taking the ek to Melbourne this weekend and want to be able to sit at 100-110 without straining the grey too much. So the question is, is a 3.55 the best option all around, or could a 3.36 be used without ruining the gearbox? And would it be too sluggish around the suburbs?
Also, do both axle seals need to be replaced?
Thanks, Jimmy

Re: hydramatic diff ratio
i may be wrong but at a guess you should be ok with the 3.36 it might hurt you on hills though, also take into consideration the height of yor tyres if you have lower profile tyres than original the 3.55 will probly only bring you back to where the ratios were originally with 3.89 and tall tyres
there was someone on here a while back that was running 2.78 with hydra and grey motor and said he had no real issues

Re: hydramatic diff ratio
Very good point Mick, anyway i'm leaving tomorrow with a 3.89 in tow so i'll just see how it goes - it's normally fine at 60mph (speedo reading) on the freeway anyway.
I just get paranoid that i''m revving it too much
