do we have a forum specifically on transmission tech?

something that has info on tranny swaps,mods,compatability,what engines and bellhousings are available....ect?

i cant find it.
right now im searching through lots of threads trying to gain info on the a340 series.
i guess maybe a drivetrain sub forum.....something.
thanx

Nope, questions like that usually get asked in the age specific forums...like in your other thread....

This may be setting you up for failure, but have you tried pirate?

^^ I realized that after I posted. Haha.

Thats probably the best info on the a340 on here youll find on YT...not alot of people like that transmission.

i understand thats probally the best info on this site,i plan on posting alot more.
my goal was a place to make it easier to find for future reference.

lets say a year from now,someone else seeks this similar info,if there was a tranny section....it would be alot eaiser to find.
tranny info is kinda hard to track down on this forum.

The company produced the NV 247 all-wheel drive transfer case, sold by Jeep as the "Quadra-Trac II". The Syracuse location was also the site which produced the original manual transaxle for the Dodge Neon and PT Cruiser (T-350), as well as manual transaxles for Chrysler minivans (T-650 & 750), most of which ended up in Europe.

example
i have a np 231 case

231 part time with low range of 2.72:1 2h/4h/n/4l

this tell me its a 2h/4h/n/4l case with a 2.72 low range.

took me awhile to type this stuff.
a np 241or would be a favorable case in a toyota.
