jonlabree Posted March 3, 2013 Share Posted March 3, 2013 Have you checked the linkage at the transmission? Link to comment Share on other sites More sharing options...

padgett Posted March 3, 2013 Share Posted March 3, 2013 Sounds more like it "thinks" you are floored. Is the 1st-2nd shift late (over 30 mph) ? If it is, check the vacuum modulator. Link to comment Share on other sites More sharing options...
Guest spongebob Posted March 4, 2013 Share Posted March 4, 2013 (edited) not sure i know what you mean padgett, ill take it for a spin later and see when it shifts..would a parts store have this "modulator"? and what do i tell them i need? the manual says i need a good one to check mine.....(thanks GM) Edited March 4, 2013 by spongebob (see edit history) Link to comment Share on other sites More sharing options...
Guest Richard D Posted March 4, 2013 Share Posted March 4, 2013 Was this the only failure mode? Did it start shifting slowly from 2 to 3, or one day it just stopped shifting to 3 or 4? How many miles does the car have on it? I am taking mine to a friend who has his own shop and specializes in Lexus/Toyota trannys and engines and I will ask him if he has any ideas. He was able to repair mine that was sometimes shuddering or slow to shift 3 to 4. Link to comment Share on other sites More sharing options...
Guest spongebob Posted March 4, 2013 Share Posted March 4, 2013 richard my reatta has 117k on it, a while back the car would drop back into 2nd on its own...a GM mechanicfound a shorted wire somewhere and he taped it up...now its doing this thing..it just happened !

DAVES89 Posted March 4, 2013 Share Posted March 4, 2013 I don't like the "over the counter" modulator from a FLAPS. I prefer the GM one. You may want to check with Jim for a used GM one if you find the price of a GM unit too high. That is if you determine you need one. Link to comment Share on other sites More sharing options...
Guest spongebob Posted March 4, 2013 Share Posted March 4, 2013 Ok it shifts out of 1st at 18 mph and out of 2nd at 25..into neutral. if some has a GM part number ill check on line for a modulator.. Link to comment Share on other sites More sharing options...
padgett Posted March 4, 2013 Share Posted March 4, 2013 Those speeds sound like the vac mod is working. I assume you have tried Seafoam TransTune ? Since the 440T4/4T60 has very little electrics (except for the TCC) it sounds like a stuck shuttle or worn band. Link to comment Share on other sites More sharing options...

Since the 440T4/4T60 has very little electrics (except for the TCC) it sounds like a stuck shuttle or worn band.My Mechanic (ASE trained) said the same thing Padgett came up with. Since it was a sudden failure it may just be a stuck shuttle or band. He also told me he has worked on a bunch of these that had been abused. Normally with maintaince good for 150,000+ miles. Good Luck! Don't give up the car if the rest is good. Link to comment Share on other sites More sharing options...
Guest spongebob Posted March 6, 2013 Share Posted March 6, 2013 i love my reatta, but its a pain to work on..i hope i can get the transmission thing worked out..reading the factory service manual isn't any helpit was written for someone that understands whats being told, and they run you in circles ..

padgett Posted March 6, 2013 Share Posted March 6, 2013 "it was written for someone that understands whats being told" - yes, service manuals and dash ones are written that way. See MIL-STD-38784 Link to comment Share on other sites More sharing options...
Machiner 55 Posted March 6, 2013 Share Posted March 6, 2013 "it was written for someone that understands whats being told" - yes, service manuals and dash ones are written that way. See MIL-STD-38784MIL-STD-38784, MILITARY STANDARD: MANUALS, TECHNICAL: GENERAL STYLE AND FORMAT REQUIREMENTS (02 JUL 1995)., This standard covers the general style and format requirements for the preparation of standard Technical Manuals (see 3.2.36 and 3.2.38) and changes to standard TMs. This includes all technical documents which are assigned a TM identification number and are to be controlled by a TM management information system or are subject to requisition from an inventory control point. In addition to ‘paper” deliverables, this standard provides for electronic delivery of data through use of the Document &pe Definitions (DTD) contained in Appendixes B through E. This general style and format standard supplements the various detail specifications for specific types of TMs and related publications and does not alone deliver any technical data. Examples at the rear of this standard are typical and may be adapted to fit the specific equipment or situation being covered.Is it any wonder?John F.
