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 time has come to mourn the death of yet another sporty car nameplate. This one doesn’t affect the North American market, and while inevitable, it’s kind of a. Eight states and Washington D.C. Have legalized the recreational use of pot, but driving high is illegal, Instamotor points out. That’s the tricky part: how do you.

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. Wouldn't take a lot of torque though.

Unicase transmissions aren't very common, in fact they fetch a decentprice if you are actually looking to buy one from a tranny shop. 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.

[ Thanks to Steve Ochs, Joe Padavano, Stephen Hooverfor this information. ] Dual Path Hydramatic Olds used the 'Dual Range Hydramatic in 1954, and 53. I'm not sure howmuch earlier they used it though. Olds used the 'Dual Coupling Jetaway Hydramatic' (I justlove thoes 50s names!) from 1956-1960. It came in two different flavors,with one model produced from 56-58, and the other from 59-60. I have acutaway picture of both in a manual of mine, and the differences lookminor.

That's right, a 4 speed auto! From the pics I have seen, it looks like it has2 torque converters in it (thus the dual coupling designation). Adobe Photoshop Cs3 Free Download Crack Keygen Serial Number. Why itdoes, I'm not really sure. The first model production run was from 1956 to 1959,the second model ran from 1959 to 1960.

Differences were minimal.After they dropped the Jetaway in '60, they used a 'ThreeSpeed Hydramatic' until the Slim Jim Jetaway two speed appeared. In 1961 the 'Three Speed Hydramatic' was adopted, with a scaleddown version used in the F-85. That tranny was used until 1963, when the2 speed Jetaway was adopted. This transmission is not related to the'slip-n-slide Powerglide' though. Pan Shape Length [ Thanks to Scott Clark for this information.

Some 1965 Jetaways havea green metal plate attached to the right side of the transmission.These numbers and letters appear as 'YY' 'XX'NNN', where YY is the last two digits of the model year, XX isthe ID (found below), and NNN is the day the transmission was built.

TH-350 has it, TH-200 does not. A fair number of the V-6cars got the TH-350.

The lighter V-6 saved enough weight that the heaviertrans could be used. On the trans, the TH-200 and TH-250 have no vacuum modulator.
