Hi guys, neighbours just picked up a standard blobeye from the auction, all is well car runs nice and smooth very quietly until engaging from 2nd gear to 3rd under heavy acceleration-seems to be very hard to find on boost but goes to 3rd from 2nd very easy any other time .any help,advice very much appreciated cheers

5 or 6 speed box

Change box and diff oils for fresh and decent stuff, it may help.

Could be a synchro, or the start of a 5 speed box deciding to throw its toys out of the pram.

Hi pal, its on a 5 speed.2nd to 3rd gear is easy and smooth,and so is every other gear only when you go for a blast will you notice the problem ..cheers

It's normal Combo trust me! Both mine and my mates old one often refuse just 3rd when changing around 6,000rpm. A few Tuners have also told me it's common.

Try Castrol Universal 75w90 Transmission Fluid (used to be Castrol Syntrax).

Really made a difference to my 5 speed. My Sti 4 used to have a notch going from 3rd to 4th above 4000rpm. Above oil cured it. Some say this oil just masks an existing problem, but if it allows the gears to mesh as they should, without crunching, it should prevent any further damage from occurring.

No guarantee that this will fix your neighbours issue, but it's worth a try at around £50 to do both the gearbox and the diff.

Hope this helps.
