I have a 58 edsel with a 410 and the single range trans. I want to change trans to dual range. I want to keep the teletouch pushbutton system. I know the dual range has an extra detent position. My thoughts are,that I can use my low position on the teletouch as D1 abd Drive as D2.
What I don't know and am looking for technical advice on whether this is possible. the distance the detent travels is the same on single and dual range units? I am looking at using a Mercury dual range from a 430 that had pushbuttons.
Anyone encounter someone that has any info on a comversion like this? Sure appreciate any technical advice. Tom

A DUAL-RANGE TELETOUCH was proposed but never produced. There was one production LINC TELETOUCH that was DUAL-RANGE and it had six buttons. FORD had so much touble, that as you know the complete system was dropped after 1958. The MERC was cable operated.
It would take some fabrication for a CRUISE-O-MATIC installation, maybe eliminating L. You would then have D2 and D1.

Thanx for your reply.
I am looking for a trans that is the large series to fit. I want to know what I can use. Are the trans from the 383 merc's also the large series? I know some of the merc's had pushbuttons,which I can't use due to them using a park release cable. Did the 1959-1961 Mercury use a cruiseomatic that didnt have a vacuum modulator? My trans uses the carb to trans rod,not vacuum modulator.
Sure appreciate any help! Tom

The CRUISE-O-MATIC was redesigned again in 1961 introducing the modulator valve. All production before that was Throttle Valve.
The MERC-O-MATIC is Single-Range whereas the MULTI-DRIVE is Dual Range. It is a stronger-heavier (main case) transmission compared to the FOM/COM. TURBO-DRIVE (Single-Range) and TWIN TURBO-DRIVE (Dual Range) were LINCOLN specific (LX).
I have no info on EDSEL other than a TELETOUCH TSB. I would guess thay were a mix of COM and MOM.

Sure appreciate the listing. The dual range all have different prefix and suffix letters. I assume the 7000 units are all large case? I know there were pushbutton and column shift options. Do you suppose that's what indicates?
I have a 58 pushbutton trans. the only numbers I found on it was PBB-7006J,no prefix. I thought That I could use it,but not familar with the park cable operation,if I could just eliminate cable. Also,the levers on trans are different. Do you know anyone that if knows if levers can be swapped?It came from a 58 Park Lane.
Not knowing details,that's why I decided to look for another trans that had a column shift. Any suggestions you may have would be appreciated. Tom

The I.D. Nos. work this way. They are similiar to a Service PN but these nos. gets one into the correct parts list in the MPC.
The Prefix (First three characters) indentify the Trans. Model. 7000 is the Basic PN for a transmission assembly. The Suffix further identifies the trans. PBL is the model no. for both the MOM and Multi-Drive (one example as 1958 was the transition year). The suffix actually differentiates one from the other.
Now, you have a 1958 CORSAIR/CITATION (410 MEL) and you want to go Dual Range (preferably MERC-O-MATIC Multi-Drive). Are you keeping the TELETOUCH or going to a column shift?

Thanx again for your research. I plan on retaining the teletouch and not go to column shift. From info I have so far,the trans I have from a 58 merc with the pushbutton won't work. That merc trans didn't have the Id tag on it. The numbers I got were off the casting that I posted earlier.
I have someone checking on a 59 merc trans. he may have one and hope he can get the Id tag info. I believe the 383 and the 430 are same case,but don't know what the different prefix and suffix numbers indicate. The chart you sent is for 58,that year had both column and pushbutton. That's what I figured were the differences on that year's model.
If this fellow indeed has a trans,I'll email the numbers to you and see what you think,if it is the correct case. I'm trying to save myself a wasted days trip. Tom

The Push Button MERC main case is unique as is the TELETOUCH EDSEL main case. What may have to happen here (now this is conjecture only as I do not have all of this period tech info) is that if the EDSEL is actually a MERC-O-MATIC Single Range, that it can be updated with the MULTI-DRIVE valve body to make it Dual Range. How you would modify the shift motor/linkage would be the problem. It is also possible to retrofit a later FMX valve body to the trans (may have to go to modulator valve) to achieve SELECT-SHIFT (P-R-N-D-2-1)(There was also a SELECT-SHIFT CRUISE-O-MATIC in 1967). With this, it may also be possible to use TELETOUCH buttons D & L for SELECT-SHIFT D & 2 as L is automatically used in SELECT-SHIFT D position.
EDSEL Shop Manuals and Parts Books are very expensive on E-BAY, so I have never tried to source a set. But I ass-u-me the E-475 had a MERC-O-MATIC behind it as it was a very stout engine.

Thanks again for your post.
You are right that the Edsel amd Merc are both same size[410 and 430] trans. They are single range.
The difference between the single and the dual is the sprag clutch feature,I see. I did ask an old trans builder about retrofitting to make a single range a dual. He told me it couldn't be done. I thought as you,that a valve body change would make it work.
The Edsel case is same as Merc with the exception of a electric solenoid to safeguard against accidental trying to engage reverse while moving forward. Most of the solenoids have failed and have been disabled. Still can use a Merc trans regardless. Tom
