2008年3月4日 · This adapter is used to mate a GM NP203 to a GM 6 Bolt Round Transmission. With this adapter plate there is no need to disassemble and drill the 6 bolt pattern into the face of the NP203, and you only lose 3/8" of Spline Engagement! **Notes** -NP203 must have the same spline count as the...

2010年10月2日 · Yup, 30 wt motor oil is correct for an NP203. The NP203 is easy to identify as it's a large cast iron housing with an aluminum tail housing. 1988 Dodge AW450 Ramcharger-318TBI-NP435-NP205-D60s

2013年4月25日 · The np203 is full time 4wd instead of the np205 which is pt 4wd. This is why I was asking about the integrity of the tcase. But if there are other options for a pass side mounted tcase that would be more durable and work with a gm trans im all ears.
