wuestion re:Tremec TRX or Magnum 6 speed transmissions in an F Body

[RT_Robb]

Hello Forum members,

I am interested in upgrading an "NP" 4 speed (mopar A833?) tranny to a Tremec TKX (?) 5 speed or Magnum 6 speed without breaking the ie bank();which one would fit an F Body without a lot of "fab" work behind a magnum v8 in a 1979 Plymouth Volare and be most cost effective per se??

Thanks in advance for any/all replies!

...Tremec TKX (?) 5 speed or Magnum 6 speed without breaking the bank...

Those transmissions are between 3 and 4 thousand dollars alone. Then you're adding hydraulic clutch bits and flywheel, disc, pressure plate, tunnel, crossmember, bushing, and related shifter mods.

Did you ever think of maybe just... Passon Performance A-855 Five Speed Transmission

Be prepared to cut up the transmission tunnel and fab a crossmember for the swap, those transmission's are tall and wide.

$$$$$$ plus the weight. Jaime really struggled with the production side

I just recently asked about an engine trans swap for my duster. the easiest direct drop in suggested for my preferences was the 727 trans.
(I wanted to keep it a 3 speed auto with an auto over though. )

tkx has a smaller case but still requires mods

I dunno?? instead of talking about what I was told, here is a link to my thread. maybe some suggestions there will help out here.


K I am wanting to buy a newer used vehicle for a more modern engine/trans swap into my 79 volare' duster/roadrunner.

Yeah, RT_Robb is asking about two different transmissions. The whole point of the TKX is the smaller size to avoid fitment issues. Can you elaborate about required mods? I'm thinking about that swap.

That's not the TKX, right?

 

[Aspen500]

Not sure exactly what you are wanting to do but, if it's to have overdrive, have you considered a Gear Vendors O/D? Less money (still not cheap though) and way fewer mods. Only an idea

 

[Greg55_99]

That's a T56 pic in an A Body but the amount of floor cutting is the same.

 

[george cobb]

lots of cutting to get it the tranny in
