Transmission

We took the Elise out of service the first week of November.

All my adult life when it came to cars, I thought I was pretty kind to the equipment. I kept my cars longer than just about anybody I knew. My brakes, tires, and clutches didn’t wear out as fast as they did for most of my friends and acquaintances.

It’s no surprise, then, that I’ve been beating myself up a bit about the Elise. I’ve had suspension failures and a bad cam. I haven’t heard of anybody else having the hub carrier plinth bolt issue, and nobody thinks it’s a maintenance issue. But after having both sides fail, I’ll be replacing the bolts every few years. The bad cam seems to be the luck of the draw. I went about 60k miles before having the problem. I’ve heard many reports of it happening a lot sooner. Then there’s my “money shift”. Pure driver error on that one.

And, now, the third gear synchro. It started going out about a year ago. Before I decided it was the synchro, I worried that it was damage resulting from the money shift. I went into third instead of fifth. Did that break my third gear? But, no, not related. More likely due to my not rev-matching. I don’t know. Anyway, the transmission is replaced at 92k miles, so it started at about 87k and 50ish track days.

But let’s go back to November. We didn’t park it until then, but I had been looking for a solution. What I ended up doing was buying a rebuilt transmission off Lotus Talk. The seller was at one point part of the Lotus Service Exchange and in this role rebuilt about 65 Elise/Exige gearboxes. (This one has the LSD, so I’m replacing same for same.) Seller says, “It had 9000-11000 miles on it when it was pulled for a notchy third gear. I installed a new synchro and inspected the rest of the gears.”

My original thought was just to get mine repaired. Michael and I could take it out of the car to save some labor costs. I talked to a number of people. I was surprised nobody wanted to do the work. The closest I got to anything like a quote on the work was nearly twice what I ended up paying for the rebuilt one. So it was cheaper to put in a repaired one with about 10k miles on it than to have similar work done to my 92k mile one.

In all my looking around, I came to the conclusion that these transmissions are notorious for third gear synchro issues. In the Lotus at least. The guy I bought mine from had two others for sale, and the one I bought the most miles on it. Searching the forums and talking to people, nobody I’ve encountered who has had the third gear synchro fail had anywhere near the mileage or track days I’ve done.

So I guess, in spite of all my repairs, I’ll continue to suffer from cognitive dissonance and believe I’m kind to the equipment.

The transmission arrived nicely boxed up. He built a frame of 2x2s with a plywood base, strapped it in so it wouldn’t jostle about, and stapled corrugation to the exterior. Unfortunately, we destroyed the box when we took it out. I wasn’t thinking about what I’d do with the one we’re taking out. I’m pretty sure now that I’m going to build this type of box for both the transmission and the motor I took out last year. Boxed up, they’ll be much easier to both move and store. I could stack them!

The whole replacement operation took a bit longer than we anticipated. My original hope was to be back on the road by Christmas, so I could participate in HPR’s customer appreciation day. We weren’t even close, but so it goes. Other than not wanting very much to work in the garage when it was cold, and it seemed all our warm weather was during the week, we also ran into a couple of minor issues.

One was the replacement transmission with where a stud mounts. The threads were damaged. Michael borrowed a tap and die set from his work and the repair was fairly easy. So we have an oversized stud in there now.

The other “minor” issue didn’t cause us any delays. I had to buy a couple of bell housing bolts. When we dove into the job, we noticed we had a few fasteners missing. Two of the bell housing bolts were gone, and so was a nut on the driver’s side motor mount. I know the race car guys are always going over their cars making sure all the nuts and bolts are properly torqued. I never worried about it, but clearly, the solid motor mounts are just vibrating the thing apart. So I guess I need to take the clam off once a year and check all the nuts and bolts.

I did a time-lapse of the clam removal. I was thinking it might be cool, but, frankly, I’m underwhelmed. I didn’t mean to leave the timestamp on the camera, but it lets you know how long the process took. I have a “quick disconnect” kit so we don’t have to take the seats out. Oh, and you may notice Michael removing a broken passenger side rear side-marker light.

I’ve only driven it around the block (before we put the clam back on — that always gets some odd looks). Going around the block isn’t a real test, but at least I know I can select all the gears. I’m quite happy to have it back now that the weather is getting nice!
