I heard something like that on early 3 ribs. Tell us Eric.

| Post subject: | Transmission Strength |
I've been surfing shoptalkforums looking for some basic/average figures on what the various stock trannies will handle in terms of power. In my search, I ran across this: Quote: A decent 1303 (late IRS, single side plate) box should cope fine with your EJ22. They are nearly as strong as a 091 and have much better street ratios. (http://www.shoptalkforums.com/viewtopic.php?t=106504)
Single sideplate car tranny almost as strong as the 6-rib?! From all of the things I've heard, I'd almost say he's crazy, but no one tried to gag him on that, so I must ask: is this true? |

I would venture out here and say this is true. I know a guy that runs a single side cover sedan transaxle behind his 2276 in his woods buggy. It holds up fairly well. I don't think the strength is "almost" the same as a 6 rib but it is a very strong trans. It is stronger than a 3 rib for sure. He likes the gearing in it and he says they are much cheaper to replace and easier to find. That much we know is true. |

6-rib has a MUCH stronger ring and pinion gear and also case strength in the diff section. It also has bigger/stronger spider/axle gears as well as a wider first gear. I used to run type 1 transmissions as well, but I would either break the case or R&P first. I also tore out some 1st gears. I do not suggest putting a lot of money in a type 1 for hill climbing. No matter how strong you make the forward gears and diff, you will still tear out the R&P or case... |

I have heard stories that the first and second gear are the same as an 091, meaning that the gears can be swapped from the car trans to use in the 091 trans. Any truth to this? |

All of the 3-ribs have the same forward gears as the early type 1 transmissions. These all have a 10 tooth first gear on the mainshaft. You can interchange any of them, including the mainshaft (which has 1st and 2nd made onto it). Some of the 3-ribs had a different mainshaft. It was bigger where it goes through the mainshaft bearing. This is easily identified by removing the nosecone and looking at the mainshaft bearing. The one with the odd shaft will not have a concave washer under the snapring. There is no washer at all. These are rare so for the most part, it will not be an issue. Some of the type 1's had fine tooth 3rd and 4th gears which created less noise but were not as strong as the coarse teeth ones. 5-rib transmissions have the same forward gears (and reverse as well) as late style type 1 transmissions. These have a 9-tooth first gear (much stronger then the 10-tooth) on the mainshaft and can be identified by a little line around the outside of the gear teeth. (or you can just count them). You can interchange these. The 6-rib transmission has the same number of teeth on 1st gear idler as the 5-rib and late type 1, but it is wider and stronger. It can be interchanged into a late type 1 transmission as long as you use the 091 1st/2nd operating slider. It will mate to the late type 1 mainshaft. This slider will also mate to the type 1 late reverse idler. Those are the only parts that you can use from a 6-rib into a type 1. The 091 mainshaft will not fit into a type 1 because it is too long. |

Definitely a lot of good info. Thanks everyone, especially Eric. So...what I'm getting from this is that I probably shouldn't count on a late type-1 to play well with a 200 hp/210 ft.lb tq. engine, correct (even for the road)? If I use anything stock it's going to have to be a 6-rib. Check. Pat |

it still isn't too hard to tear up a 091 mainshaft (first gear) |
