Just bought a 95 LS400 and want to do a transmission fluid change as gearchanges feel a little lumpy to me - Halfords had nothing matching Type IV, my local Toyota dealer said they only had it in huge drums but were willing to sell it to me if I supplied some suitable containers to fill up.
Spoke to a local independent who suggested Comma ASW and according to their website it does match Type T-IV, just wondered if anybody had used this themselves with any tales of woe or recommendation.
Comma ASW Type T-IV
