Lately been thinking of going back to a stick trans, not sure why, just thinking, anyways I have been looking for a NP`440 trans, GM`s version of the a833 mopar overdrive, looks like a muncie, but with a final ratio in fourth of .73, they seem to be little elusive, found two on ebay at a premium price, and two locally one severely rusted main shaft, no linkage, the second has no linkage and no bell housing, these are bell housing specific, also thought just go ahead and put in a t`10 or muncie and be done with it, they have really come down in price lately because everybody is going to OD either 700r4 or the T5, then I got to looking at the AX15, used in `92 to 99 jeeps, both 2 and four wheel drive units, they are 5 speed trans, torque rating at 330 lbs,( same as the standard GM t`5 ) now I know a lot of jeep owners that have them with no trouble in the off road community, ( we`re not far from the Rubicon trail ), they make a chevy bell housing for them or a adapter plate for the chevy bell housing to mate them up, you use all standard factory GM parts for the clutch, the shifter is a center top mount that would come up thru the floor just 2 inches back behind the original location of the shifter, the trans weighs in at 95 lbs, the drive shaft slip yoke will have to be changed I believe the shaft is slightly smaller. Found one locally last night on CL a `96 for $200...think that that might be the ticket, anybody have one in their Jeep, or other vehicle, opinions welcome...? Note the AX15 trans has a 3.83 first gear and a .79 fith gear. that equates to 2100 RPM at 65 for my gears.
