Re: TO INSTALL A TREMEC TKX TRANSMISSION UPDATE : THE DEATH OF AN ENGINE !!! Shortly after the last picture where I was going to modify the engine block plate to clear the oil drain plug I decided to drain the engine oil What I found was a complete DISASTER IN- PROGRESS !! The magnetic oil drain plug came out mega- covered in metal !! oil pan lots of metal there .. using camera probe found damage number seven intake roller lifter and camshaft, also found possible block crack same location number seven intake lifter bore .. engine has been removed pending going back to my machine shop !! https://cimg5.ibsrv.net/gimg/www.thi...3a273b139d.jpg metal on drain magnetic drain plug https://cimg2.ibsrv.net/gimg/www.thi...a4a6a75096.jpg metal in oil pan https://cimg7.ibsrv.net/gimg/www.thi...b31b61c727.jpg damage to camshaft https://cimg3.ibsrv.net/gimg/www.thi...23e01fd505.jpg block crack |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Oh man that's terrible. :( |
Re: TO INSTALL A TREMEC TKX TRANSMISSION OH NO!!!! :( I hope you get it back up and running soon |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Ive had this trans installed for a few weeks and just got the y-pipe made for the exhaust. 42-42.5" inch driveshaft needed to work with this trans (w/ 9" rear) and 1.5" trans mount from energy suspension. This makes for plenty of clearance and a 2" rubber mount/bushing put the top of trans within 3/8" of trans tunnel. Shift pattern is wider than a 6 speed so its taking a bit to get used to. Hanlon Motorsports supplied the shifter relocation arm for tremec shifter that centered the shifter almost perfect. Lakewood bell 15020 is what I had so I made it work. The OP of this thread has the better suited lakewood bell and if I did it again I would use that one for hydraulic TOB lines etc. I had gotten the used bell a few years ago used and the threaded holes were not great and wouldnt hold torque so I welded in the bolts from inside. Wiring was simple with 2 connector from MDL. Reverse is 2 wires and electric speedo 2 more. No reverse lockout opr skip shift BS. I also made a switch from aluminum flywheel to steel. It made a world of difference in how the car takes off in first gear. Much smoother and easier. Im running as Mcleod RXT and its engages better than previous RST I had. Im sure there are a few things im missing so let me know and id be more than happy to help. Heres pics of install, I also installed lemons custom headers and 3.89 gears with this trans swap so it took a bit more time than expected. Enjoy! https://cimg5.ibsrv.net/gimg/www.thi...bee27bea09.jpg https://cimg8.ibsrv.net/gimg/www.thi...88579b0e8c.jpg https://cimg9.ibsrv.net/gimg/www.thi...c36bedd38c.jpg https://cimg1.ibsrv.net/gimg/www.thi...611f8cbca7.jpg https://cimg2.ibsrv.net/gimg/www.thi...8d2b2450e4.jpg https://cimg3.ibsrv.net/gimg/www.thi...aca434850d.jpg https://cimg2.ibsrv.net/gimg/www.thi...22190585fd.jpg |
Re: TO INSTALL A TREMEC TKX TRANSMISSION looks great! how do you like it now that you have driven it for awhile? |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Drives great and shifts smooth. Steel flywheel is much better all around even if losing a few hp to the wheels. Going to be trying a short throw shifter in a few weeks. |

Re: TO INSTALL A TREMEC TKX TRANSMISSION thats a hooker blackheart crossmember with 4l60e adapter plate..but it still needs some mods to make it line up with trans mount which you cant really tell from pics. I drilled out trans mount and elongated the holes in plate. The hanlon motorsport modified shifter I just took out last week for a short throw. Ive got about 750 miles on that. That pieces alone from hanlon is $125. then you need to take the tremec shifter apart and install offset shifter arm mount. I can save you the headache of doing this and sell you the complete shifter with a pro 5.0 shifter arm. Its not cut down so it will be about an inch taller than that in the pics. Ill let it go for $120 + shipping, PM me or email is famioso15@aol.com |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Those Oxygen-Sensors should be moved upwards at a 45 degree angle... Not at 90 degrees, like they are currently. |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Vorteciroc that sure wouldnt change a damn thing lol. Been running good for over 1200 miles and no issues with o2. Innovate specs 3-9 oclock on the top side of clock. One side is 2:30 and other is about 9:45. Bad angle of pics, but oh well, that all doesnt matter as my Accel DFI NTK o2 sensor I installed in the 5" intermediate pipe. Thanks for the heads up thou, ive done this header o2 thing a few times over the past 20 years lol |

Re: TO INSTALL A TREMEC TKX TRANSMISSION what short throw shifter did you go with, how do you like it? |
Re: TO INSTALL A TREMEC TKX TRANSMISSION I have a tkx in my 87 formula behind a Pontiac 428. Wondering also what short throw shifter you used? I am using the stock one that come with the Modern Driveline kit. It’s ok, but a little shorter throw would be nice. |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Short throw is from Driveline Components. I added a spacer and used a T56 handle from pro 5.0. https://cimg8.ibsrv.net/gimg/www.thi...23ed6f4635.jpg |
Re: TO INSTALL A TREMEC TKX TRANSMISSION I've been doing research to do this swap into my 88 IROC to replace the junk T5 thats in it. This will be very helpful to me when it comes time for me to do it! Thank you! I do plan to utilize the Factory T5 Hydraulics though |
Re: TO INSTALL A TREMEC TKX TRANSMISSION Is the Hydraulic clutch kit necessary for the swap, or can it be done without? Also, what benefits do you gain from having a hydraulic vs mechanical clutch? Can a stock T-5 driveshaft be used or will a custom one be in order? |
Re: TO INSTALL A TREMEC TKX TRANSMISSION So I noticed that this shifter moves the handle STRAIGHT back, which is the same as the TKX shifter in the Hemmings YouTube series "IROC rehab". But in the photos of the transmission right out of the box (earlier in this thread), the shifter is different and moves it forward and toward the driver. I assume this is NOT the correct position for the shifter and that to center it in the hole in the console, it needs to be moved straight back? In this video from American Powertrain, the shifter appears to be WAY forward in the opening in the console: Can anybody provide some clarification? Very interested in doing this for my 86 IROC. Thanks. |

Re: TO INSTALL A TREMEC TKX TRANSMISSION Did the original shifter hole have to be enlarged/cut to install the TKX? |
Re: TO INSTALL A TREMEC TKX TRANSMISSION The AMERICAN POWERTRAIN white Lighting shifter is adjustable to 16 different positions I found one that I liked and slid everything home . I even used the shifter handle from my T5 Hurst shifter, NO MODIFICATION TO THE FLOOR ARE NECESSARY. :driving: For temporary test drive reasons I even reused stock drive shaft with a Ford C6 transmission yoke and cross/fit u-joints MY-92-RS |

The advantage of hydraulic verses mechanical linkage , is less pedal effort and no adjustment of clutch linkage needed, FYI Tremec recommends roller bearing style pilot bearing instead of solid bronze For Test drive reasons I reused stock T5 drive shaft AFTER replacing the YOKE with a FORD C6 yoke and adapter universal joint Good luck with your build MY-92-RS :driving: |

Re: TO INSTALL A TREMEC TKX TRANSMISSION New Drive shaft is a bad *** little piece was included with Transmission.. each one is custom built to your Measurements.. Aluminum or steel same price . since mine is a Drag race setup with slicks I went steel , with solid 1350 ujoints https://cimg3.ibsrv.net/gimg/www.thi...abc4188913.jpg |
