Olds FAQ -- Transmissions Transmissions Submit corrections and additions to this information to. Automatic Transmission Identification On theRH side of the transmission, just above the pan, is an ID plate, about ½'in size. Gently wash off the grunge and look for the ID code painted onand stamped in as well. It'll be of the form 'OA-##-1234' where the 1st letter tellsthe car make: O is for Oldsmobile, B is for Buick, P is for Pontiac, etc.,and the second letter denotes the application. Generally speaking, thehigher the letter, the better. Some will have three letter designations, andthe first letter can vary, such as L or J or F, etc. The ## numbers is the year of the car: 68=1968, etc.

No mystery here.The last 4 digits [1234 above] are the transmission unit number, not unlike theengine unit number found on the oil fill tube of 68-up engines. Also, for 1968 and up applications, the VIN derivative will be stampedinto the LH side of the transmission, between the two ribs and just above thepan. This will be the same number/letter combination that the engine received-see engine ID above for particulars. Under GM's new transmission nomenclature, the first digit signifiesthe number of speeds, the second place is either L or T (for longitudinal -RWD or transverse-FWD, and no, they no longer make the longitudinal FWDToro transmission), the next two are somehow related to the transmission'storque carrying capacity (higher is better), and the E designateselectronic, as in computer controlled.

The electrical connectors on the TH-350C, TH-250C, and TH-200C arefor the lockup torque converter clutch. Note that the 'C' suffix onthe transmission model signifies it is a lockup torque convertermodel (i.e. TH-350: no lockup, TH-350C: lockup).

The reverselight switch is part of the neutral safety switch assembly. Thesame switch is used to tell the ECM that the vehicle is in park/neutralas opposed to in gear (idle control). GM uses two bellhouse patterns (on real cars, RWD, '64 or so to theend of the V-8, outside of the early hydramatics): • Chevy. Looks like a mansard [barn] roof. Pointy at the top.• Everyone else. Olds, Buick, Pontiac, Cadillac. Not pointy on top, kinda flat,with about 7' between the top 2 holes.

I believe the indexing pins are commonto both patterns, not quite sure on that. The dual bolt patterns showed up when GM started to consolidate it'stransmission operations and use 'Chevy built' transmissions in BOPapplications and 'Hydramatic Built' transmissions in Chevy applicationas. The 4L40-E, 5L40-E, and 3L40-E have replaceable bellhousings, but aremainly European applications. The 5L40-E is a 4L40-E with another gear inthe middle. This transmissionis being built exclusively for BMW for their 3 and 5 series vehicles. The4L40-E is used in many including Opel, Cadillac Catera, Holden, and BMW M3,and some 3 and 5 series.Probably adaptable with some modifications as they both have replaceablebellhousings.

Unicase transmissions aren't very common, in fact they fetch a decentprice if you are actually looking to buy one from a tranny shop. Alien Implant Bcd3000 Mappers more. I knowall TH-2004R's that I have seen are unicase (makes you wonder why the 700'saren't), but I do know they started way earlier than 1980 - my original1970 TH-350 is a unicase.

Actually - there never was a BOP TH-700-R4 (there is a BOP 4L60-E due toreplaceable bellhousing - started in 1995).I believe the 4L80-E uses Chevy mainly but since it is sold to othercustomers, it might have another bolt pattern available.
