h151 vs h152

[dr_dobro]

I did the ratio calcs and the H153f seems like a good contender for my particular vehicle. The H152f would also do well for my needs. At my elevation, with the turbo and 35s, the A343f is doing a bangup job of keeping it in OD bulk of the time. Basically, this transmission doesn't piss me off anymore which makes me think I'm after the same performance using a 5sp manual. Crawl ratio is irrelevant to me as all the manuals have silly 1st gear. Admittedly, I find myself setting the cruise at 80 mph due to the trannny staying in OD as I go over smaller hills.

If my numbers are inaccurate, please lmk.

Great chart, Did you created this chart based on stock 3.7 or 4.1 differential gears?
I am also in the hunt for a new transmission as well just planing to run 37’s

The chart is based on my 4.56 diff gears which can be seen on the sheet as well.

Hice los cálculos de relación y la H153f parece una buena opción para mi vehículo. La H152f también me vendría bien. A mi altura, con el turbo y los 35s, la A343f funciona de maravilla manteniéndola en sobremarcha la mayor parte del tiempo. Básicamente, esta transmisión ya no me molesta, lo que me hace pensar que busco el mismo rendimiento con una manual de 5 velocidades. La relación de arrastre me resulta irrelevante, ya que todas las manuales tienen una 1.ª marcha absurda. Admito que suelo poner la velocidad de crucero a 128 km/h porque la transmisión se mantiene en sobremarcha al pasar por cuestas más pequeñas.

Si mis números son inexactos, por favor avíseme.

SGreetings. Which Cruiser models have the H153? Since what year has the H152 been available in the new 70 Series? Thanks
