![]() ![]() Compared with the Hilux, the Tacoma is engineered with a greater priority on ride quality, handling, comfort, and safety over ruggedness and payload capacity. However, I don't have an automatic transmission laying around, so I enlisted some help over on TercelOnline, a forum for Tercels and Paseos that I've been on for ages.The Tacoma was introduced in the US in February 1995 (March 1995 market launch) as a replacement for the Hilux, which prior to this was marketed in the US under the name Toyota Pickup. Throwing a 2.821 differential ratio into my extra Paseo 5 speed (C150) would give me a very nice 1525 rpm at 45 mph, and 2200 at 65 mph. Yes, I'm no fan of automatics.Īs it turns out, the 4 speed auto transmissions (only put in Paseos and some 95+ Tercels, the rest had 3 speeds) have a 2.821 differential ratio. Their accursed names won't be mentioned here, but they start with an A and end with an utomatic. ![]() Dummy me, I had completely forgotten about the other transmissions that were available in the Tercels and Paseos. So, I thought that was the best I could do for quite a while, until I started digging around even more. Doing so would give me 1700 rpm at 45, and 2450 at 65 mph. I'm not 100% sure that it would physically all fit up, but I assume so. The best option I have then is to take that C151 5 speed, and put my C141 differential gearing in it. ![]() If I'm going to pull an engine and trans out, I'm going to want a bit more. Using this trans would get me down to 1800 rpm at 45 mph, 2600 at 65 mph. Here are the gear ratios of the Tercels & Paseos (they both use interchangeable transmissions). This has a taller 5th gear, but a higher ratio differential. The easiest swap is a 5 speed from a 95+ Tercel (aka C151). ![]() As you can see, at 45 mph (my main commuting speed) the engine is spinning at almost 2100 rpm. Here is a screen shot from a calcultor I've made and used over the years. The stock 4 speed (aka C141) isn't absolutely horrible, but its far from ideal for mileage. One of those things is swap in some taller gearing. Thus, I've been thinking about all the different mods I'd like to do and making a to-do list for myself. I've mentioned it several times, but I'll be working on my 1993 Tercel in the not horribly distant future. ![]()
