Now With More Manual Transmission



Trust me when I say there is no more detestable a sensation than being slowly overrun by cold tranny fluid.

This isn't my first rodeo. I have, in the past, pulled any number of transmissions, both automatic and manual, and no matter how many times I do the deed, I'm always astounded at the staggering preponderance of fluid a slusher can stash away in its unknown voids. I started the madness of converting this 1989 Ford Mustang from a four-speed automatic to a five-speed manual by dropping the pan on the old gearbox and letting the super-fried automatic transmission fluid bleed out into a drain pan.

Pulling the old box out of the car was as simple as keeping everything supported while I removed the driveshaft, unbolted the bellhousing from the engine block and sent the one crossmember that supported the transmission packing. But wrestling the contraption from under the car unleashed a small lake of brackish ATF that threatened to flash flood the basement. Trust me when I say there is no more detestable a sensation than being slowly overrun by cold tranny fluid. Please hold your "that's what she said" jokes until the conclusion of our program.

Pulling a Ford four-speed automatic
Cleaned T5 manual transmissionFour-speed automatic vs five-speed manual

The T5 manual transmission had come back from the shop with all of its questionable internals sorted for a reasonable price, but I was still in need of a proper bellhousing. Whereas the '87 Thunderbird rolled from the factory with a nice squishy hydraulic clutch, the Mustang made due with a cable set up. Thanks to an alignment of the crappy car heavens, a cable bellhousing showed up on Craigslist for the paltry fee of $20. After a fun conversation with a gentleman who informed me he was quitting his job to "get into the gun business," I had what I thought was the last bit I needed to sew the machine together. A little time with a wire wheel on the air grinder resulted in a gussied up case and a bellhousing to match. I shot the whole shindig with clear engine enamel to keep the assembly from going cruddy again anytime soon.

I sourced an el cheapo clutch to use for the time being, and had a friend machine the flywheel from the turbo 2.3 for a grand total of $100. From there, nothing was left to do but hitch up my britches for the swap with me thinking I had all my rubber duckies in a row. After I cleaned up the toxic lake of goo that poured from the old automatic, dropping the flywheel in was as simple as unbolting the old flex plate and placing the flywheel in its place with ARP hardware.

In this case, assuming makes me the ass with no way to support the transmission he just spent two hours wrestling into place.

Time for me to let you in on one of the secrets of playing around with old Ford four-cylinders: As it turns out, there's massive parts support for the engines and an equivalent base of knowledge thanks to the fact that circle track racers have been abusing the 2.3 for generations. As a result, picking up go-quicker bits for even the naturally aspirated four-pot is as simple as running down to your local speed shop. While I had anticipated a week of infuriated searching for the flywheel hardware, I had ARP fasteners in my hand for $8 after one phone call – a pleasant change from the infuriating parts hunt I'm familiar with from the International.

With the clutch and flywheel snugged into their new homes, getting the gearbox to mate up to the 2.3 was just a matter of wrestling it under the car, onto the transmission jack and into place, except I had neglected one very important piece of this puzzle: the crossmember. I was under the impression the T5 would get along just rosy with the piece that supported the old automatic, but in this case, assuming makes me the ass with no way to support the transmission he just spent two hours wrestling into place. I came up with a somewhat questionable temporary support comprised of a piece of oak flooring and a pair of valiant screwdrivers, while I tracked down the component I need.

As it turned out, sourcing a manual transmission crossmember for a foxbody was no cheap exercise, so rather than deal with the roached bushings of a used piece, I tracked down a polyurethane mount and handsome adjustable aluminum crossmember to fill in the blank spaces. Despite the chunky nature of both bits, the pieces weigh about what the old stamped steel and rubber hardware did, plus, the new parts look like a piece of modern art lurking around under the otherwise decrepit Mustang. Who doesn't like a good Easter egg every now and again?

The stock mounting brackets required a bit of fudging to accommodate my larger hardware, but otherwise, the install went in as smooth as could be. I dropped in a salvaged driveshaft from a V8 car for the time being and turned my attention toward actually getting the gearbox to work in its new home. Stay tuned for swapping pedal boxes, installing the clutch cable and a fancy new shifter.

      Color me impressed. Always refreshing to see staff from automotive websites actually turning wrenches, as opposed to the armchair auto 'enthusiasts' who's biggest automotive interaction was pumping gas (since full service was not available. The last transmission work I did was on a vintage mid-engine Italian. I got my wife (there's a woman!) to help me carry the transaxle to the bench.

      My wife's going to kill you when these articles inevitably lead me to rekindle my turboford project.

      It's too bad there aren't 380 comments on this post like the Silverado article because in my opinion, these anecdotes are the most meaningful. They are well written and appeal to the true enthusiast. I too hope to fix up a controversially designed car, a 91 Geo Metro. I, like you, need to stop listening to the haters and continue on. It will have a 10 pound turbo with an upgraded suspension... in other words, Sleeper.

      Esslinger is a great source for Ford 2.0 and 2.3 parts. A simple, cheap upgrade for your engine would be the roller tappets from the Ranger 2.3, assuming you also swtich to a roller cam. And when you go to pull the cam, don't forget the lockscrew on the backside of the last bearing tower.....

      Why is this not a weekly series yet?! More! I need my fix of fixin'... IMHO this is far more worthy of Autoblog bandwidth than "The List."

      There are ways to do this without the spills. Also I don't think OSHA would approve of the way you use that jack. I have done worse.
