Lube job.
This is excellent. I've used it now in two 1980s classic cars now which had tired and probably neglected gearbox oil services. It has after a couple of changes bought the boxes back to smooth easy changing, where as other same spec gear oil just didn't do the trick. The manufacturer's claims in my cases work.

A premium oil that will probably last the rest of my old VW vans life. Same price as local major chain retailer.

High quality Castrol oil
I always use Castro oil in my vehicles from my motorbike to my truck. Have never changed transmission oil before so bought this and what a difference. For reference I have an old Mitsubishi l200 pickup truck so requires regular maintenance Oil quality is fantastic and has not let me down. For ease I also purchased a syringe to help refill the gear box and transfer case which made it much easier. I would never not use Castrol oil

Not bad, definite shift improvement. Good bottle design.
Used a few of these in a 2ZZ-GE Toyota Celica 6-speed 'box and it noticeably improved shifting feel. Smoother and more direct. Whether this was the oil itself or the fact it was changed I don't know. Well worth the hour-or-two to do the job. I used a hand oil pump but the bottle has a multi-stage lid that could be used to pour oil directly into a gearbox/diff if you have space, which is a nice touch.

Si tienes un audi a4 b6 de 5 velocidades (awx) y quieres sustituir la valvulina de la caja de cambios, esto es lo más parecido al lubricante original que vas a encontrar en el mercado. Probé otros antes de marcas reconocidas y los tuve que sustituir por el tacto duro y brusco de la palanca de cambios. Con este aceite esos problemas han desaparecido, las marchas entran suaves y sin forzar, tanto en frío como en caliente. Para hacer el cambio se necesitan 3 botes de un litro, aunque siempre sobra algo.
