So my swap is now complete, now for the wiring...so i kept my 4t60e tranny from my 97 monte ls with my series 2 L67(from a 98 gtp). I picked up a wiring harness from a 98 z34 at the junkyard, my problem is the wiring harness connectors for the tranny don't match up to my stock tranny. I DO have the old harness with the correct connections is this something i can cut and splice together? Or what's my best bet

 

throw that 4t60 in the scrap bin. be all sorts of hell making it work. plus it wouldnt hold up anyway. i killed a 4t60 with a 3400. go ahead and 4t65 swap

 

Figured as much unfortunately...i have a 4t65e-hd from the gtp the only worked in 1st and reverse. Are they worth rebuilding?

 

yeah theyre not expensive to rebuild. im running a non hd l36 4t65 in my l67 swapped 97 monte myself
what yr gtp?

 

I agree with l67ss. Yea there worth rebuilding so go ahead and do that. Depending on how much power your trying to make will be the deciding factor on if upgraded parts are needed or not.

Contact dave at triple edge performance for your trans needs. Yea you might have shipping cost to get it to him and get it back bit he is hands down the best trans builder for the 4t65 ever.

 

wait....was the speedo working in the gtp?

 

Yea i believe it was working but im not 100 percent sure. The gtp is a 98 btw. Did you have to modify anything to fit your 4t65e in your 97? (passenger side axle)

 

My guy down here in Fl quoted me $550... Thats pretty good right

 

550 for a rebuild is a GREAT deal.

You will need custom axles on both sides. I used the inner axles of a GTP and outer axles of a Monte. Lots of fun.

 

actually on an hd 4t65 you can ues a stock 97-99 monte z34 pass side axle
