General Maintenance

Mileage: 255,634

Today my MR2 got a much needed oil and transmission fluid change.  I had noticed that going into gear was grinding, sometimes.  Gear shifts now feel smooth once again after the fluid change.  I had been at least a month since I driven her, you kinda forget how much fun it is.

Leaks

Not much has been going on with my MR2 recently, she’s been taking me to work and back with no issue. Recently I noticed a small puddle under the car when pulling it out of the garage.  It looks like I have an oil leak, maybe from between the head and block, also some kind of fluid was coming out from in between the engine and transmisison, not cool.

Clutch Line

Pardon the messy engine bay but I got a braided clutch line installed today 🙂

Major Progress

Since the last post I purchased another C-160 transmission, got it modded, and mated up to the motor.  I was able to repair the wheel bearing and that seems to be working well.  I also dropped the gas tank, checked that it was clean inside, and re installed it.  The motor is now installed and the car runs.  Today I got the tags registered and I can drive it on the road.  For pictures of the progress click on the “repair photos” link to the right.

Transmission seal replaced, brake MC replaced

Got my replacement seal today. I think it’s the same seal as on the C-50/C-52. I also got my rebuilt master cylinder in today and its install seemed to go without a hitch, the brake system is bled and the pedal feels good.

Seal is out, new seal is in and we went for a test drive around the neighborhood! She seems to pull a bit harder than I remember 🙂

Transmission leak

Thanks for the links Drumhead, I ended up ordering a rebuilt cylinder from Advance Auto Parts but it won’t be in for another 3-4 days. In the meantime I figured I would look at the leaky axle. I found some crud on the tulip that might have been causing there to be not the best seal but I find it difficult to think that was the cause of the problem. As best as I can tell the seal looks to be in good condition. What are your guy’s thoughts?



Transmission Mods / Motor Install!

Tonight I picked up my old transmission as I’ll be needing a few parts from it. It was mid-repair as the shop was looking for parts.

HUGE progress today! I got the transmission modified, bolted to the motor, and got the motor in the car! It was a very long day and I know for sure I am going to sleep well tonight. Tomorrow will consist of hooking up coolant lines, wiring harness, filling fluids, and trying to start her up.




New Transmission

Today, a day early, my “new to me” C-160 showed up in the mail. Everything looked to be in great condition. I made a Friday appointment at my local performance shop to have the rework done to the transmission housing (hold drilled, flange for seal welded on). I plan to pick up my old C-160 from the shop it’s been at tomorrow to get the reworked selector shaft and end cap. Tonight I took the motor off the stand and got the flywheel, clutch, and pressure plate re-installed. The motor is ready for its transmission. If the mod goes well on Friday I should be looking to install the motor this Saturday. I still have a few loose ends to tie up including getting gas, a battery, checking that I have all other fluids (oil, coolant, transmission fluid, brake fluid), picking up the selector shaft seal from Toyota, and checking on insurance and registration. Phew, it’s getting close!



The C-160 is down for the count :(

So driving home from work yesterday I noticed a strange sound coming from the engine bay. As most MR2 owners know, you are always listening for little sounds or funny smells So some further diagnostics while driving home revealed that the sound changed with speed and also load. So while giving the car a little bit of gas (to load the drivetrain) the sound got a bit quieter. Then once I let the car coast there was a lound sort of ticking / grinding sound.

So I pulled over, popped the engine lid and reved it up a bit (to some strange looks from some construction workers). No strange sounds coming from the engine. So I get it limped home and jack up the back end. First thing I do is check the fluid by pulling the overflow bolt. I lil bit of fluid comes out meaning the tranny is full. Simple solution number 1 eliminated.

So I put the car in gear and spin one wheel. The other responds as it should spinning in the other direction and I can hear something is not right in the transaxle.

So thinking it through, it can’t be the clutch, as the clutch was engaged during my test (and therefore wouldn’t be spinning at all). So I am thinking something in the “transaxle” part of the transmission like the diff or something.

So now I have to drain the fluid, take out the axles and tulips, and see if I can find anything wrong. If that doesn’t work then I have to drop the tranny…ugh.

Transmission mount

Well it took a lil more than “a strip of flat steel and a couple of drilled holes” but you are looking at a modified tranny mount for the C-160 transmission to fit in an MKI MR2!

Board member “truebluemr2” did all of the fabraction and has done an awesome job. He has been an invaluable help during my swap! 🙂 I will post more pics later.
